Detailed Description

MythDisplay is a wrapper around platform dependant display functionality. It can only be created by MythMainWindow and the single instance is owned by the MythMainWindow object.

Note: There is no locking in MythDisplay. It should never be used from anywhere other than the main/UI thread.

Bug:: When using Xinerama/virtual screens, we get the correct screen at startup and we successfully move to another screen at the first attempt. Subsequently trying to move back to the original screen does not work. This appears to be an issue with MythMainWindow relying on MythUIHelper for screen coordinates that are not updated and/or subsequent window movements moving the window into the wrong screen. Much of the MythUIHelper code needs to move into MythDisplay.

Todo:: Complete handling of screen changes. We need to handle several cases. Firstly, when the main window is moved (dragged) to a new screen. This generally works but need to check if all display details are updated (VideoOutWindow is currently hooked up to the CurrentScreenChanged signal - so video window sizing should work without issue). Various other parameters need updating though e.g. refresh rates, supported rates etc Secondly, when a new screen is added and the user has configured a multiscreen setup - in which case we might want to move the main window to the new screen. There are various complications here. Currently switching windows is triggered from the settings screens - which initiate a teardown of painter/render/UI etc. We cannot do that from random parts of the UI or during video playback.

◆ EstimateVirtualAspectRatio()

double MythDisplay::EstimateVirtualAspectRatio ( )

Estimate the overall display aspect ratio for multi screen setups.

Note: This will only work where screens are configured either as a grid (e.g. 2x2) or as a single 'row' or 'column' of screens. Likewise it will fail if the aspect ratios of the displays are not similar and may not work if the display resolutions are significantly different (in a grid type setup).; Untested with a grid layout - anyone have a card with 4 outputs?

◆ GetAspectRatio()

double MythDisplay::GetAspectRatio	(	QString &	Source,
		bool	IgnoreModeOverride = `false`
	)

Returns current screen aspect ratio.

For the vast majority of cases we should be using the physical display size to compute the actual aspect ratio.

This is currently overridden by:-

a custom, user specified aspect ratio for a given display mode. This feature is considered legacy as I don't believe it should be needed anymore, complicates both the code and the user 'experience' and offers very limited values for the override (4:3 and 16:9).
a general override for setups where the aspect ratio is not correctly detected. This generally means exotic multiscreen setups and displays with invalid and/or misleading EDIDs.

If no override is specified and a valid physical aspect ratio cannot be calculated, then we fallback to the screen resolution (i.e. assume square pixels) and finally a guess at 16:9.

◆ GetCurrentScreen()

QScreen * MythDisplay::GetCurrentScreen ( )

Return a pointer to the screen to use.

This function looks at the users screen preference, and will return that screen if possible. If not, i.e. the screen isn't plugged in, then this function returns the system's primary screen.

Note: There is no special case here for the case of MythTV spanning all screens, as all screen have access to the virtual desktop attributes. The check for spanning screens must be made when the screen size/geometry accessed, and the proper physical/virtual size/geometry retrieved.

◆ SetWidget()

void MythDisplay::SetWidget ( QWidget * MainWindow )

protected

Set the QWidget and QWindow in use.

Certain platform implementations need to know the QWidget and/or QWindow to access display information. We also connect to the QWindow::screenChanged signal so that we are informed when the window has been moved into a new screen.

Note: We typically call this twice; once before MythMainWindow is shown and once after. This is because we need to try and ensure we are using the correct screen before showing the window, and hence have the correct geometry etc, and once after because the QWindow is sometimes not created until after the widget is shown - and we cannot connect the screenChanged signal until we know the window handle.
