|

// With this very dirty workaround, we can fix lxqt/lxqt bug #204, #205, and #206.
|
|
// Qt 5 has two new regression bugs which breaks lxqt-panel in a multihead environment.
|
|
// #40681: Regression bug: QWidget::winId() returns old value and QEvent::WinIdChange event is not emitted sometimes. (multihead setup)
|
|
// #40791: Regression: QPlatformWindow, QWindow, and QWidget::winId() are out of sync.
|
|
// Explanations for the workaround:
|
|
// Internally, Qt mantains a list of QScreens and update it when XRandR configuration changes.
|
|
// When the user turn off an monitor with xrandr --output <xxx> --off, this will destroy the QScreen
|
|
// object which represent the output. If the QScreen being destroyed contains our panel widget,
|
|
// Qt will call QWindow::setScreen(0) on the internal windowHandle() of our panel widget to move it
|
|
// to the primary screen. However, moving a window to a different screen is more than just changing
|
|
// its position. With XRandR, all screens are actually part of the same virtual desktop. However,
|
|
// this is not the case in other setups, such as Xinerama and moving a window to another screen is
|
|
// not possible unless you destroy the widget and create it again for a new screen.
|
|
// Therefore, Qt destroy the widget and re-create it when moving our panel to a new screen.
|
|
// Unfortunately, destroying the window also destroy the child windows embedded into it,
|
|
// using XEMBED such as the tray icons. (#206)
|
|
// Second, when the window is re-created, the winId of the QWidget is changed, but Qt failed to
|
|
// generate QEvent::WinIdChange event so we have no way to know that. We have to set
|
|
// some X11 window properties using the native winId() to make it a dock, but this stop working
|
|
// because we cannot get the correct winId(), so this causes #204 and #205.
|
|
//
|
|
// The workaround is very simple. Just completely destroy the window before Qt has a chance to do
|
|
// QWindow::setScreen() for it. Later, we recreate the window ourselves. So this can bypassing the Qt bugs.
