remove space around qToolButton

[jkwok678]

How could I remove the border around the qToolbutton? Is there another way apart from using stylesheets?

Hi
if you set widget size to the same as icon size then it covers all of the button ( minus 1 pixel for the hover effect)

[jkwok678]

Is that done in the designer? I've been hand-coding it so far, and the only methods I've seen is set Max & Min height & width.

Hi
Yes 100% Designer.
Just properties.

[jkwok678]

Is there a way to replicate this in code ?

[mrjj]

@jkwok678

yes. open setupUI() you see in mainwindow constructor.
You can press F2 on the name to go there
then you can take the code.

@jkwok678 I'm not sure about this, but does setAutoRaise(true) act as you expected?

[jkwok678]

@mrjj
Ah, I think you misinterpreted what I mean, I've hand coded all the buttons and didn't use a ui file.
So I want to try replicate your button that i saw in the image using code.

[mrjj]

@jkwok678
Yes i fairly sure i did :)
its
button1->setFixedSize(100,100);
button1->setIconSize(QSize(100, 100));

for 100x100 icon / button

@Bonnie
Thanks for the suggestion, it works in a way, but once the button is highlighted you can still see the border around the QIcon in the QToolButton. So the size of the button is still the same, I was hoping to shrink the size of the button, to being much closer to the size of the QIcon which is 16x16. I would prefer to have maybe 1/2 pixel border around the button. But also allow the button to expand if the screen resolution/ screen size is high.

Ok then DONT use setFixedSize to set size but just the normal ones

[jkwok678]

@mrjj
With this implementation is the setFixedSize more of a default/intitial size?
So when I have code that allows the button to resize, it can still do so?

[mrjj]

@jkwok678 said in remove space around qToolButton:

setFixedSize

Will set to a fixed size so nope, it wont resize then
so dont use it if you want toolbuttons to grow

[jkwok678]

What's the normal ones? I don't see just a set Size function in the documentation.

@jkwok678

Hi
setGeometry and
resize

but if you put them in layout anyway, its pointless as then they scale and
icon gets border again since now iconSize is not matching anymore.

[jkwok678]

So, what could I do to have the button have the same size as the QIcon, or at least just less blank space?

[mrjj]

@jkwok678
well
button1->setFixedSize(100,100);
button1->setIconSize(QSize(100, 100));
set button to 100x100 and same with icon.
botton stay that size.

[jkwok678]

Would it be able to do that and also expand?As in when the button expands the Icon could expand as well? Or perhaps switch to a different Icon that us higher resolution?

[mrjj]

Hi
Sadly no.
If you want such things, make a custom button that does it.

However, Qt has support for HIRES displays that do scaling etc.
and QIcon can have hires version to be used on such displays
https://doc.qt.io/qt-5/highdpi.html

but this has nothing to do with you want icon to cover all of the button at all times :)
That is not a hires thing, in my opinion :)

here is example of custom button
https://stackoverflow.com/questions/31742194/dynamically-resize-qicon-without-calling-setsizeicon

It scales the cion to fit at any given time.
As you can see its not much code.
