Changing app's QPushButtons' backgrounds with global stylesheet breaks its dimensions.

[AlexNevskiy]

Hello all!

Imagine that I want all buttons in my prog to have a nice gradient look. And I use a global app stylesheet for this purpose. But something not understandable is going on when I'm trying to control the buttons' background through it.

If I have buttons in horizontal layout with spacer, and set the next app stylesheet

QPushButton {
    background: lightblue; 
    border: 1px solid blue; /* need for full overpainting */
}

then widths of all of the buttons flow away, and buttons with a little text become very small.

If I add a line to the stylesheet:

min-width: 80px;

or, just

width: 80px;

then buttons with small text become ok, but buttons with long text not expand and their texts are partially hidden.

So, how to change background for all buttons and not to break its dimensions?

Perhaps add some padding. E.g. padding: 5px;

Or perhaps a large maximum width.

@Tink I tried paddings, it didn't help me.

then all the buttons will be unnecessary large

@AlexNevskiy hmm... perhaps you need to change the sizePolicy?

So, I have found some sort of solution. Just need to set width of expanding spacer to minimum (0 for example). And it works some how.

Which policy will make it work?

Makes sense.

Well i have most of my widgets on preferred since i dont understand the effects well enough:)
But if you add a pushbutton in designer it has horizontal: minimum.
