Hi.
I found that if in setGeometry() method call hide() or show() on widgets inside
layout then this leads to recursion of layout.
What do you think on this problem? May be it is good suggestion to Qt
developers to remove this recursion, because of it is sometimes useful to hide
some widgets
Hello,

Dear All,
I have a problem in my application, I'm using Qt 4.8.5 and QML on our ARM
freescale platform (QWS server, not X11).
I have a TextEdit component in my QML page, and when I click on it to assign
focus, the focus is assigned but I cannot see the cursor blinking.

Hi Igor,
Your problem makes sense. Hiding and showing widgets triggers a layout
recalculation, and the layout uses setGeometry to position the widgets. It
sounds unusual to change widget visibility in a setGeometry override. I
suggest to use a flag to prevent the recursion yourself.
OK, I'm not familiar with QML QtQuick at all yet, only quite recently
started using Qt as an alternative for MS. If those support OpenGL core
profile 4+ then I'll have to take a look when I have the time, for now I
have to stick with Qt Creator.
So the context is that QtWidgets

That's exactly the magic keyword here, the static method of
QWidget::createContainerWidget!
That's
QWidget::createWindowContainer()
to be correct ;)

According to this blog post:

never use the QWidget::createWindowContainer() :) use QQuickWidget instead.

But if I am not mistaken under the hood a QWindow is also used as base for
e.g. a QMainWindow.
It is just the lowest common and most lightweight denominator for
interaction with the underlying

Hi.
How to force layout to update geometries of items in it if some items
changed theirs sizeHint property?
For example if I rotate rectangle I want layout to update geometry of
this rectangle.
I’ve tried:
layout-invalidate();
layout-update();
There is a QWindow under the hood for each top-level widget, but it is not done
via inheritance. The QWindow and QWidget hierarchies are distinct.
The description from Oliver covers the situation pretty well. One thing worth
noting in addition is that using QWindow for rendering OpenGL (or

Thanks, this discussion has been really useful, I haven't found anything
written giving the larger picture, just nuts and bolts

Regarding the idea of using MDI and QWindow for child wnds seems to stumble on
the fact that QMdiSubWindow class is a QWidget based
class too. There

That don't seem to be the case, QMainWindow inherits from QWidget,

Just a quick question about using QHash with pointers.
Lets say I have the following snippet:
//===
QWebView *view;
QHashint, QWebView * hash;
for(int i=0; i10; i++) {
view = new QWebView(this);
hash.insert(i, view);
}
go do something meaningful
//or do a hash.clear();
We are generating on-screen animations in Qt 4.8.6 widgets on Windows
(just redrawing, based on a repeating QTimer). Does Qt4 or Qt5 proper

Yes, you do need to delete them. You can keep them as scoped_ptr instead of
raw pointer.
