Toolbar spacer does not expand to the right corner

@mrjj Thank you! Here's the output (I have given my spacer object the name "spacerName"):

Qtitan::DockToolBar::

Qtitan::DockToolBarExtension::

@TommyTLC
Ok so it is still there :)
Then i would
qDebug() << "size" << qDebug() << spacer->geometry();
and it will show something like
QRect(747,339 75x23)

as it could be fun to see its location and size.

[TommyTLC]

@mrjj This is where my spacer is located/its size: QRect(0,0 1180x480)

[mrjj]

@TommyTLC
so its at o,0 and 1180 wide o.O and almost 500 in height.
but we clearly dont see that.
can you try
qDebug() << "vis" << spacer->isVisible();

i was wondering if this happens due to
spacer->setMinimumWidth(1180);
as i have seen widgets do odd stuff when not room enough.

[TommyTLC]

@mrjj vis false

[mrjj]

@TommyTLC
ok so its get hidden for some odd reason.
do you use the do anything to the spacer variable after it has been inserted ?
also try
spacer->show();
after its gone. ( like via a button)
and lets see what happens.

[TommyTLC]

@mrjj This is all I do with the spacer:

QWidget* spacer = new QWidget();
spacer->setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Preferred);
spacer->setMinimumWidth(1180);
m_fileToolBar->addWidget(spacer);

it gets created, I set the SizePolicy and the minimumWidth and then I assign it to the toolBar.

[mrjj]

@TommyTLC
Ok so its not hidden by user code.
Could you try a smaller minimum and see like
spacer->setMinimumWidth(200);

I know its not the goal but just to see if it still happens.

@TommyTLC said in Toolbar spacer does not expand to the right corner:

in the >> I only see my m_aboutAction

you do not see the style combo either?

Did you overload resizeEvent?

Does the "Configuration" label on the left have something special?

If it goes into >> then it will be hidden. I'm not sure this test is conclusive

[TommyTLC]

@mrjj By changing the minimum size I see the spacer:

But the items to the right can still be hidden by resizing the window:

[TommyTLC]

@VRonin Correct, the only thing I see by clicking the ">>" is the m_aboutAction.
The configuration label is an action. When clicked it generates a dialog you can interact with.
I am not sure what overlading the resizeEvent means.

[mrjj]

Hi

• I am not sure what overlading the resizeEvent means.

Like for MainWindow, you have that function implemented in your code.

I have a feeling it the
setMinimumWidth that is the culprit of this.

[TommyTLC]

@mrjj Getting rid of the minimumWidth only leaves a small gap between the items in the toolBar. I don’t know what else I could try :(

[mrjj]

@TommyTLC
Ok so it dont grow ?

Hmm. What version of Qt are you using ?

the code VRonin works perfectly in 5.15

But you get another result ?

[TommyTLC]

@mrjj I’m working on the 5.15. His code DOES work perfectly, but for some reasons it has issues with my project. The spacer does not push the items all the way to the right. That’s why I was trying to set its minimumWidth.

Hi,

Then you should start by using @VRonin's code in place of yours. Once you confirm it's working, you can step by step replace the widgets with the ones you are using until it breaks again.
