QGroupBox is filled with too much space.

@Pippin
Well if you want it 20 , then
LocalIp.setMaximumHeight(20)
so at most 20.

you could also limit the left side to prevent it from making lower box smaller

Pippin

@mrjj Okay thanks, now I get this: http://i.imgur.com/Oyt3gnT.png

It's better but still poorly spaced. I've tried to change the spacing of DirectLineBoxLayout but the result remains the same.

mrjj

@Pippin
oh, hmm, it divides the area (of the container) between them.
You could insert a VerticalSpacer to push them up.

@mrjj Ok but isn't there any way to actually reduce the area? Why does it have to be bigger than all the widgets together?

mrjj

@Pippin
The area is also scaled to its container layout so that is where it get its height.
maybe QLayout::setAlignment can make it stack more to the top but
i mostly just insert a spacer.

Pippin

@mrjj QLayout::setAlignment doesn't seem to work with DirectLineBoxLayout. I'll try to find another way.

It sometimes is very frustrating how full of bugs Qt is.

mrjj

@Pippin
Well you can set Maximum Height on the layout to force area smaller.

It is possible to build using a widget as place holder.
Have a look at this.

Hi,

Maybe a silly question but since it's for IP addresses, why not use a QLineEdit ?

Pippin

@SGaist Good point, I use QLineEdits now. My problem remains though: http://i.imgur.com/raW29vW.png

Neither QVBoxLayout::addStretch (result is unchanged) nor QGroupBox::setMaximumHeight (result: http://i.imgur.com/FklMI9g.png) seem to work here.

I'd rather have the extra space disappear rather than add a spacer or something. The smaller the window, the better.

SGaist

For the layout of your dialog, I think you should have a look at QFormLayout

Pippin

@SGaist I can't use QFormLayouts because I need to display a Connect QPushButton as well as a Host QPushButton. Or is there a way around this?

Pippin

Well never mind, I'll just drop the IP info so that there's no more bug.

It is absurd how Qt has that many bugs. Before coding tip-top things, Qt's coders should make sure that the most basic (BASIC) things actually work. I wish I didn't have to use Qt. It is so very overrated. Sorry for that, but I'm both exasperated and disappointed. That's not the first unsolvable problem I've come across.

SGaist

You would put your QLineEdit and two QPushButton in a QHorizontalLayout. QFormLayout::addRow supports also layouts.
