Detailed Description

Bus for sending requests to any kind of window. It could be a NativeWindow or an Editor window.

Member Function Documentation

CanToggleFullScreenState()

virtual bool AzFramework::WindowRequests::CanToggleFullScreenState ( ) const

pure virtual

Can the full screen state of the window be changed/toggled?

Returns

True if the window can enter/exit full screen, false otherwise.

GetClientAreaSize()

virtual WindowSize AzFramework::WindowRequests::GetClientAreaSize ( ) const

pure virtual

Get the client area size. This is the size that can be rendered to. On some platforms this may not be the correct size until Activate is called.

GetDpiScaleFactor()

virtual float AzFramework::WindowRequests::GetDpiScaleFactor ( ) const

pure virtual

Returns a scalar multiplier representing how many dots-per-inch this window has, compared to a "standard" value of 96, the default for Windows in a DPI unaware setting. This can be used to scale user interface elements to ensure legibility on high density displays.

GetFullScreenState()

virtual bool AzFramework::WindowRequests::GetFullScreenState ( ) const

pure virtual

Get the full screen state of the window.

Returns

True if the window is currently in full screen, false otherwise.

SetFullScreenState()

virtual void AzFramework::WindowRequests::SetFullScreenState ( bool  fullScreenState )

pure virtual

Set the full screen state of the window.

Parameters

[in]

fullScreenState

The full screen state to set.

SetSyncInterval()

virtual bool AzFramework::WindowRequests::SetSyncInterval ( uint32_t  newSyncInterval )

pure virtual

Sets the sync interval which tells the drivers the number of v-blanks to synchronize with Returns if the sync interval was successfully set
