Open()

bool MythXDisplay::Open

(

)

Open the display.

Note

If the '-display' command line argument is not set both this function and Qt's xcb platform plugin will pass a null string to XOpenDisplay - which will in turn use the DISPLAY environment variable to determince which X11 connection to open. If the '-display' command line argument is used, we set s_QtX11Display and the argument is also passed through to the xcb platform plugin by Qt (via the QApplication constructor). So in all cases, the following code should open the same display that is in use by Qt (and avoids linking to QX11Extras or including private Qt platform headers).

GetDisplayDimensions()
