[4.2.2] minimize widgets in qworkspace ?
Message 1 in thread
Hi Qtees,
I've got several MDI windows floating in my QWorkspace ... and the
following problem: "widget->showMinimized()" is ignored.
How can you minimize these widgets, so only the "bar" is visible? Note
that I don't them to relocate to the bottom of the main window.
tia,
r.

More information:
I add the windows as following:
addWindow(widget, Qt::Tool | Qt::WindowShadeButtonHint);
I can successfully get the state with:
bool x = widget->isMinimized());
cheers,
r.

Are you minimizing the subwindow, or the widget inside?
Have you tried parentWidget()->showMinimized()?

I'd like to minimize some of the "subwindows" inside the main window (for comprehension: when loading a "perspective").
parentWidget()->showMinimized() doesn't show any effects as well ...
I assume there's some mystery concerning that "ShadeButton" thing, but I have no clue what else I could try ...
thx,
r.

Indeed, ther is a little yet interesting effect: The icon next to the "X" (to close the window) indicates that the (sub-) window is minimized, however, it isn't. How I can I avoid this inconsistent state?
thx,
r.

If you call showMinimized() on the window, not the widget inside, the window
should be minimized. If this doesn't happen, it's likely to be a bug.
Could you please send some code that shows the problem?

In absence of Rene, here's a code sample demonstrating the problem:
class MainWindow : public QMainWindow {
public:
MainWindow(QWidget* parent = 0) : QMainWindow(parent) {
QWorkspace* workspace = new QWorkspace(this);
setCentralWidget(workspace);
QLabel* label = new QLabel("See what I mean?");
QWidget* mdi = workspace->addWindow(label, Qt::Tool |
Qt::WindowShadeButtonHint);
addToolBar("MDI")->addAction("Minimize", mdi,
SLOT(showMinimized()));
}
};
As described by Rene, programatically minimizing an MDI window with Tool
and WindowShadeButtonHint flags only toggls the shade button symbol, but
does not really minimize the window. And to make matters worse, the
symbol is only redrawn when I move the mouse over the window...
Please have a look. Is this a bug? (I begin to think so)
Thanks a lot.

I filed a bug report on the task tracker, issue number is #146659.
