How To Make App Automatically Fit To Screen Mac

  • Apple in iOS 14 redesigned the Home Screen for the first time in a long time, introducing an App Library that lets you hide apps, widgets that can be placed among apps, and more. This guide walks.
  • Basic resize in Windows. As you can see in the image below, there are two buttons for resizing a window automatically. Minimize - Clicking this button, which looks like a dash, collapses the window onto the Taskbar.; Maximize / Resize - Clicking this button, which looks like a box or two boxes, toggles the window between full and nearly full (not maximized) screen.

Hover your pointer over the full-screen button in the upper-left corner of a window. Or click and hold the button. Choose ”Tile Window to Left of Screen” or ”Tile Window to Right of Screen” from the menu. The window then fills that side of the screen. Click a window on the other side of the screen to begin using both windows side by side. Some Mac users really enjoy full screen mode for apps and windows, so much so that they might want to make Mac apps open in full screen mode automatically. While there is no system wide setting in Mac OS to make apps default to opening in full screen mode, there is a workaround trick that will allow many apps to open directly into full screen.

You can screenshare on a Mac to quickly share your screen in several ways, which can be useful when coordinating a project or sharing a presentation. However, sometimes just opening and closing it during a single login session will have it automatically re-open in full-screen. So, to answer the OP, I think the default is apps should resume as they were. IPhoto's irregular behavior is likely a bug in Lion.0, which one hopes will be fixed in 10.7.1.

I recently switched from a 15' MacBook Pro (2007 model) to the latest 13' MacBook Pro (2009, unibody model). After transferring my iTunes library to the new laptop, I found that the size of the iTunes window exceeded the size of the screen (the 15” MBP had a 1440x900, while the 13” MBP has a slightly smaller 1280x800). This meant I was unable to grab the bottom right corner of the window to resize it:

Unfortunately, the maximize button in iTunes only cycles through Previous Size and the Mini Player mode; at no point does it actually maximize the window to fit the screen!

Note: As Ondrej commented below, you might be able to fix this by simply holding down the Alt/Option key and pressing the zoom/maximize button (the green button).

I tried installing an application called RightZoom which changes the behavior of the maximize button in OS X by maximizing the window to fill the screen (as opposed to simply maximizing for “best fit”). However, that did nothing to change the behavior of iTunes.

After searching the web for solutions and finding nothing, I remembered a trick I had used in the past on Windows computers: Change the display resolution to something smaller, thereby forcing the operating system to resize windows to fit the new resolution. Then, after the OS resizes the windows, change the resolution back to the original. Of course this only works if the original resolution is not already set for the lowest one (it most likely isn't).

To my relief, this trick worked perfectly! When I switched to a smaller resolution, the iTunes window was resized to fit the smaller screen.

For your reference, here are the steps:

  1. Launch System Preferences -> Displays
  2. Select a smaller resolution
  3. iTunes (or any other application) will be resized to fit the smaller resolution
  4. Change the resolution back to the default

Before you build a canvas app in Power Apps, you specify whether to tailor the app for a phone or a tablet. This choice determines the size and shape of the canvas on which you'll build your app.

After you make that choice, you can make a few more choices if you select File > App settings > Screen size + orientation. You can choose portrait or landscape orientation and screen size (tablet only). You can also lock or unlock the aspect ratio and support device rotation (or not).

Those choices underlie every other choice you make as you design screen layouts. If your app runs on a device of a different size or on the web, your entire layout scales to fit the screen where the app is running. If an app designed for a phone runs in a large browser window, for example, the app scales to compensate and looks oversized for its space. The app can't take advantage of the additional pixels by showing more controls or more content.

If you create a responsive layout, controls can respond to different devices or window sizes, making various experiences feel more natural. To achieve responsive layout, you adjust some settings and write expressions throughout your app.

Disable Scale to fit

You can configure each screen so that its layout adapts to the actual space in which the app is running.

You activate responsiveness by turning off the app's Scale to fit setting, which is on by default. When you turn this setting off, you also turn off Lock aspect ratio because you're no longer designing for a specific screen shape. (You can still specify whether your app supports device rotation.)

To make your app responsive, you must take additional steps, but this change is the first step toward making responsiveness possible.

Understand app and screen dimensions

To make your app's layouts respond to changes in the screen dimensions, you'll write formulas that use the Width and Height properties of the screen. To show these properties, open an app in Power Apps Studio, and then select a screen. The default formulas for these properties appear on the Advanced tab of the right-hand pane.

Width = Max(App.Width, App.DesignWidth)

Height = Max(App.Height, App.DesignHeight)

These formulas refer to the Width, Height, DesignWidth, and DesignHeight properties of the app. The app's Width and Height properties correspond to the dimensions of the device or browser window in which your app is running. If the user resizes the browser window (or rotates the device if you've turned off Lock orientation), the values of these properties change dynamically. The formulas in the screen's Width and Height properties are reevaluated when these values change.

The DesignWidth and DesignHeight properties come from the dimensions that you specify in the Screen size + orientation pane of App settings. For example, if you select the phone layout in portrait orientation, DesignWidth is 640, and DesignHeight is 1136.

As they're used in the formulas for the screen's Width and Height properties, you can think of DesignWidth and DesignHeight as the minimum dimensions for which you'll design the app. If the actual area available to your app is even smaller than these minimum dimensions, the formulas for the screen's Width and Height properties ensure that their values won't become any smaller than minimums. In that case, the user must scroll to view all of the screen's content.

After you establish your app's DesignWidth and DesignHeight, you won't (in most cases) need to change default formulas for each screen's Width and Height properties. Later, this topic discusses cases in which you might want to customize these formulas.

Use formulas for dynamic layout

To create a responsive design, you locate and size each control by using formulas instead of absolute (constant) coordinate values. These formulas express each control's position and size in terms of the overall screen size or relative to other controls on the screen.

Important

After you write formulas for the X, Y, Width and Height properties of a control, your formulas will be overwritten with constant values if you subsequently drag the control in the canvas editor. When you start to use formulas to achieve dynamic layout, you should avoid dragging controls.

In the simplest case, one control fills an entire screen. To create this effect, set the control's properties to these values:

PropertyValue
X0
Y0
WidthParent.Width
HeightParent.Height

These formulas use the Parent operator. For a control placed directly on a screen, Parent refers to the screen. With these property values, the control appears in the upper-left corner of the screen (0, 0) and has the same Width and Height as the screen.

Later in this topic, you'll apply these principles (and the Parent operator) to position controls inside other containers, such as galleries, group controls, and components.

As an alternative, the control can fill only the top half of the screen. To create this effect, set the Height property to Parent.Height / 2, and leave the other formulas unchanged.

If you want a second control to fill the bottom half of the same screen, you can take at least two other approaches to constructing its formulas. For simplicity, you might take this approach:

ControlPropertyFormula
UpperX0
UpperY0
UpperWidthParent.Width
UpperHeightParent.Height / 2
LowerX0
LowerYParent.Height / 2
LowerWidthParent.Width
LowerHeightParent.Height / 2

This configuration would achieve the effect that you want, but you'd need to edit each formula if you changed your mind about the relative sizes of the controls. For example, you might decide that the top control should occupy only the top one-third of the screen, with the bottom control filling the lower two-thirds.

To create that effect, you'd need to update the Height property of the Upper control and the Y and Height properties of the Lower control. Instead, consider writing the formulas for the Lower control in terms of the Upper control (and itself), as in this example:

ControlPropertyFormula
UpperX0
UpperY0
UpperWidthParent.Width
UpperHeightParent.Height / 2
LowerX0
LowerYUpper.Y + Upper.Height
LowerWidthParent.Width
LowerHeightParent.Height - Lower.Y

With these formulas in place, you need only change the Height property of the Upper control to express a different fraction of the height of the screen. The Lower control automatically moves and resizes to account for the change.

You can use these formula patterns for expressing common layout relationships between a control, named C, and its parent or a sibling control, named D.

Relationship between C and its parentPropertyFormulaIllustration

How

Hierarchical layout

As you construct screens that contain more controls, it will become more convenient (or even necessary) to position controls relative to a parent control, rather than relative to the screen or a sibling control. By organizing your controls into a hierarchical structure, you can make your formulas easier to write and maintain.

Galleries

If you use a gallery in your app, you'll need to lay out controls within the gallery's template. You can position these controls by writing formulas that use the Parent operator, which will refer to the gallery template. In the formulas on controls within a gallery template, use the Parent.TemplateHeight and Parent.TemplateWidth properties; don't use Parent.Width and Parent.Height, which refer to the overall size of the gallery.

Container control

You can use an experimental feature, the Container control, as a parent control. To turn this feature on, select File > App settings > Advanced settings.

Consider the example of a header at the top of a screen. It's common to have a header with a title and several icons with which your users can interact. You can construct such a header using the Container control, containing a Label control and two Icon controls:

Set the properties for these controls to these values:

PropertyHeaderMenuCloseTitle
X00Parent.Width - Close.WidthMenu.X + Menu.Width
Y0000
WidthParent.WidthParent.HeightParent.HeightClose.X - Title.X
Height64Parent.HeightParent.HeightParent.Height

For the Header control, Parent refers to the screen. For the others, Parent refers to the Header control.

Having written these formulas, you can adjust the size or position of the Header control by changing the formulas for its properties. The sizes and positions of the child controls will automatically adjust accordingly.

Components

If you use another experimental feature, named Components, you can construct building blocks and reuse them throughout your app. As with the Container control, the controls that you place within a component should base their position and size formulas on Parent.Width and Parent.Height, which refer to the size of the component. More information: Create a component.

Adapting layout for device size and orientation

So far, you've learned how to use formulas to change each control's size in response to the available space, while keeping controls aligned relative to each other. But you might want or need to make more substantial layout changes in response to different device sizes and orientations. When a device is rotated from portrait to landscape orientation, for example, you might want to switch from a vertical layout to a horizontal one. On a larger device, you can present more content or rearrange it to provide a more appealing layout. On a smaller device, you might need to split up content across multiple screens.

Device orientation

The default formulas for a screen's Width and Height properties, as this topic described earlier, won't necessarily provide a good experience if a user rotates a device. For example, an app designed for a phone in portrait orientation has a DesignWidth of 640 and a DesignHeight of 1136. The same app on a phone in landscape orientation will have these property values:

  • The screen's Width property is set to Max(App.Width, App.DesignWidth). The app's Width (1136) is larger than its DesignWidth (640), so the formula evaluates to 1136.
  • The screen's Height property is set to Max(App.Height, App.DesignHeight). The app's Height (640) is smaller than its DesignHeight (1136), so the formula evaluates to 1136.

With a screen Height of 1136 and a device height (in this orientation) of 640, the user must scroll the screen vertically to show all of its content, which might not be the experience that you want.

To adapt the screen's Width and Height properties to the device orientation, you can use these formulas:

Width = Max(App.Width, If(App.Width < App.Height, App.DesignWidth, App.DesignHeight))

Height = Max(App.Height, If(App.Width < App.Height, App.DesignHeight, App.DesignWidth))

These formulas swap the app's DesignWidth and DesignHeight values, based on whether the device's width is less than its height (portrait orientation) or more than its height (landscape orientation).

After you adjust the screen's Width and Height formulas, you might also want to rearrange controls within your screen to better use the available space. For example, if each of two controls occupies half of the screen, you might stack them vertically in portrait but arrange them side by side in landscape.

You can use the screen's Orientation property to determine whether the screen is oriented vertically or horizontally.

Note

In landscape orientation, the Upper and Lower controls appear as left and right controls.

ControlPropertyFormula
UpperX0
UpperY0
UpperWidthIf(Parent.Orientation = Layout.Vertical, Parent.Width, Parent.Width / 2)
UpperHeightIf(Parent.Orientation = Layout.Vertical, Parent.Height / 2, Parent.Height)
LowerXIf(Parent.Orientation = Layout.Vertical, 0, Upper.X + Upper.Width)
LowerYIf(Parent.Orientation = Layout.Vertical, Upper.Y + Upper.Height, 0)
LowerWidthParent.Width - Lower.X
LowerHeightParent.Height - Lower.Y

Screen sizes and breakpoints

You can adjust your layout based on the size of the device. The screen's Size property classifies the current device size. The size is a positive integer; the ScreenSize type provides named constants to help with readability. This table lists the constants:

How To Make App Automatically Fit To Screen Mac
ConstantValueTypical device type (using default app settings)
ScreenSize.Small1Phone
ScreenSize.Medium2Tablet, held vertically
ScreenSize.Large3Tablet, held horizontally
ScreenSize.ExtraLarge4Desktop computer

Use these sizes to make decisions about your app's layout. For example, if you want a control to be hidden on a phone-sized device but visible otherwise, you could set the control's Visible property to this formula:

Parent.Size >= ScreenSize.Medium

How To Make App Automatically Fit To Screen Mac Shortcut

This formula evaluates to true when the size is medium or larger and false otherwise.

If you want a control to occupy a different fraction of the screen width based on the screen size, set the control's Width property to this formula:

This formula sets the control's width to half of the screen width on a small screen, three-tenths of the screen width on a medium screen, and a quarter of the screen width on all other screens.

Custom breakpoints

The screen's Size property is calculated by comparing the screen's Width property to the values in the app's SizeBreakpoints property. This property is a single-column table of numbers that indicate the width breakpoints that separate the named screen sizes:

In an app created for tablet or web, the default value in the app's SizeBreakpoints property are [600, 900, 1200]. In an app created for phones, the value is [1200, 1800, 2400]. (The values for phone apps are doubled because such apps use coordinates that are effectively double the coordinates used in other apps.)

You can customize your app's breakpoints by changing the values in the app's SizeBreakpoints property. Select App in the tree view, select SizeBreakpoints in the property list, and then edit the values in the formula bar. You can create as many breakpoints as your app needs, but only sizes 1 through 4 correspond to named screen sizes. In formulas, you can refer to sizes beyond ExtraLarge by their numeric values (5, 6, and so forth).

You can also specify fewer breakpoints. For example, your app might need only three sizes (two breakpoints), so the possible screen sizes will be Small, Medium, and Large.

Known limitations

The authoring canvas doesn't respond to the sizing formulas created. To test responsive behavior, save and publish your app, and then open it on devices or in browser windows of various sizes and orientations.

If you write expressions or formulas in the X, Y, Width, and Height properties of a control, you'll overwrite those expressions or formulas if you later drag the control to a different location or resize the control by dragging its border.
