Windows

Window

Windows are the main object in an app's interface.

Primary Windows​

Primary Windows are what shows up when your app is opened, and displays the main functionality.

  • Primary Windows shouldn't depend on anything, closing one should not close others.

  • Apps should restrict themselves to one Primary Window.

  • All Primary Windows should be able to be resized.

  • Try to make the default size of your Primary Window match the desired amount of content your app needs.

Secondary Windows​

Secondary Windows are used for complementary content to the Primary Window, such as About or Preferences.

  • Secondary Windows should always be modal to a Primary Window, appearing "attached" to it and centralized.

  • Closing a Primary Window should close any Secondary Windows associated with it.

  • Avoid stacking Secondary Windows.

  • Avoid complex content on a Secondary Window, and don't make it bigger than the Primary Window.

Window Sizing​

Primary Windows should be able to get to the extreme size of 360×266px for purposes of compatibility with mobile Linux users.
