Re: [Interest] Custom-shaped QDialog or similar
Thanks to both of you for your hints.
I am now modifying the Window Flags example, in order to have it my way.
For this proof of concept, I am trying to do two things:
- Have the custom-shaped window
- Move the window where I want: beside the Quit button.
However, something's wrong here. I am using QRegion to define the shape,
and moving it with move().
If I set the window type to Qt::Tool I still have the window title, but
I can see the clipping working just fine. When I set the type to
Qt::Tooltip or use Qt::FramelessWindowHint, the whole window disappears!
Moreover, I am unable to move it where I want. I know it is some kind of
coordinates misunderstanding here...
Can anyone enlighten me? Code follows.
Cheers!
void ControllerWindow::updatePreview()
{
//...
QPoint b = quitButton-mapToGlobal(quitButton-pos());
pos.setX(b.x() + quitButton-width() / 2);
pos.setY(b.y() + quitButton-height() / 2);
previewWindow-move(quitButton-mapToParent(pos));
}
PreviewWindow::PreviewWindow(QWidget *parent) : QWidget(parent)
{
//...
QVectorQPoint pts;
pts.push_back(QPoint(0, 10));
pts.push_back(QPoint(36, 10));
pts.push_back(QPoint(36+10, 0));
pts.push_back(QPoint(36+20, 10));
pts.push_back(QPoint(296, 10));
pts.push_back(QPoint(296, 266));
pts.push_back(QPoint(0, 266));
QPolygon p(pts);
setMask(QRegion(pts));
}

I'd say no: if a user clicks elsewhere, it should disappear, probably. It's the first time I'm trying something like this, so any suggestion is more than welcome! If you are using a Mac, that kind of window is called a popover. We don't have support for it yet in Qt, but it should be in Qt::WindowFlags eventually (but only on the Mac). Yes you can fake it with Qt Quick, and you could draw the outline with the Canvas API, but probably it's easier to use BorderImage because of the shadows. See qtdeclarative/examples/quick/imageelements/content/ShadowRectangle.qml for example, but you will need an image with the pointy part already done. Make it as wide as the maximum-width popover you will ever want, so you can use horizontalTileMode: BorderImage.Repeat without ever repeating the pointy part. The height won't matter as much. If the popovers sometimes go upwards then you might need two different images. Since the pointy part is always inside another window, you don't necessarily need a shaped window for the popover, but a separate Window will allow the popover to extend outside the main window if necessary. Maybe use a QtQuick Window, set color: transparent and then provide the frame yourself with BorderImage? Later on you can remove that and set the new window flag when it's working. But since this is a bit complex I'm beginning to wonder if we should provide a reusable Popover in QtQuick.Dialogs. ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
Re: [Interest] Custom-shaped QDialog or similar
This would be easiest with Qt Quick but the shaped clock example is a good starting point if you want to use widgets.
