How do I add a statusbar widget to a dialog in the ui designer?

[lansing]

I have a well established dialog ui and I want to add a status bar to the bottom. But apparently there is no QStatusBar to choose from in the tool box. And there is no option to promote a class to QStatusBar.

I have tried the trick told on link stackoverflow to add a dummy widget first then manually change the object to use QStatusBar class in the generated ui header file. But the problem is every time I make a change in the designer again and try to run it, it will change back to the dummy class.

Hi
Well its only possible via code.
You simply insert in after setupUI() been run in constructor
QStatusBar *bar = new QStatusBar(this);
ui->somelayout->addWidget(bar);

Often you need a layout to keep it to the bottom but sounds like you
already have that.

Thanks it works. I added a layout to the bottom of the ui, and then in my cpp file I added the statusbar to the layout and it showed up. But somehow it's still not sticking to the bottom.

Hi,

What kind of layout do you use in your widget ? How are you using it ?

Hi i fixed the problem. It was caused by one of the initial functions in my cpp that outputed a layout onto the ui, which has not been constrained by the layout of the main widget.

@mrjj How to access this statusbar for showing message or adding a progressbar

@Rututraj
Hi
well an easy way is just to use a member variable.

so instead of
QStatusBar *bar = new QStatusBar(this); // local variable

we do
bar = new QStatusBar(this); // memeber variable

and in .h (in the class) we have
QStatusBar *bar = nullptr; // moed to be a member

and then you can just use bar-> to talk to it.

@mrjj Thanks :)

After 5 years it is still not possible to populate the status bar from the designer?
