stretching and anchoring of a widget
In my centralWidget I want to have a widget that is anchored to the top left and is stretching along with the main window (/centralWidget).
I can't seem to find how to do that inside the QT Creator design view.
Do I have to do that programmatically?
(using QT Creator 3.4.3 with QT 5.5.0 under linux)
usually you can do this using layouts.
Can you post a sketch of what you want achieve??
The thing is that in the Qt Creator design view there's no way to set anchors or stretching with the layout, as far as I managed to find.
Here's an image of what I want to have:
The green part is the widget, as you can see even when the window get bigger the widget still fills the width of the parent.
I hope that makes it clear.
The green widget should be set to preferred (expand width) and fixed (fixed height) with minimum/maximum values.
Have you tried
// after ui setup ui->centralWidget->layout()->setAlignment(Qt::AlignTop);
on your centralWidget's Layout? More on flags, here.
I hope that helps
The problem is that the green widget isn't resizing when the window is and so its width stays fixed, even though the sizePolicy for it is:
- horizontal policy: preferred
- vertical policy: fixed
- horizontal stretch: 1
- vertical stretch: 0
I haven't used the
Qt::AlignTopas the widget stays aligned to top as it is, that's not an issue, only the width is the problem.
I just want it to fill the parent.
I suggest to use
Expandingas Horizontal Policy
@mcosta that seems to have no effect on things.
the same result as before.
