[SOLVED] Resizing Custom Widgets in a Layout Leaves Empty Space Between Widgets

[Bolt2strike]

@SGaist Are you meaning to say apply a layout directly to the widget as in QWidget::setLayout(QLayout *)? I've just checked the documentation and I'm not quite sure what effect this has/what it does. Could you please elaborate a little bit more?

Edit: After reading your post again and thinking about it a bit more, do you mean that I should have a layout as a member of Pod? If this is correct in what you are saying, I think I have not explained correctly, The spacing issue is not within the pods themselves but rather between pods.

[SGaist]

If you manage all your pods like the widgets inside them, then you need to do all the mathematics to ensure they are placed and spaced correctly. That's why I suggest using a layout manager inside them and also to handle them

@SGaist @Chris-Kawa ..... Still not seeing your point, and yes now that I think about it it probably would have been better to have another layout as a member of Pod. But, as for managing placing and spacing, I don't get it, I just construct the object in a QList<Pod *> named PodList and subsequently place it into the layout, then they need not be moved again. I'm not sure if I've mentioned this previously but, the issue with the empty space comes in when I resize TextLabel, ImageLabel and their scroll areas.

    QList<Pod*> PodList;
    for (int p=0; p!=NumPods; p++)
    {
        PodList.insert(p,new Pod(0,0,400,150,this));
        MainLayout->insertWidget(p,PodList.at(p));
    }

*MainLayout is the layout in the highest level scroll area

Here I'll also include a picture to provide additional context to my issue

Since you don't use a layout manager, you also need to take into account the position of your widgets when you resize

[Bolt2strike]

@SGaist Okay. But, if I've adjusted the size of the widgets inside the v box layout, shouldn't it resize to fit its children (OR is there a fixed space within the layout that I can position Pods in)? As evidently it doesn't, how can I create this behavior? And yes, I've tried setting size policy to fixed size.

[SGaist]

If the children of your widgets are not themselves handled by a layout manager, then no, they won't do anything automatically

[Bolt2strike]

@SGaist What? If a widget and all its children in a position above that of another widget were to uniformly decrease in size so that they take up less vertical space expanding downwards but maintain the same position of being in the top left, just like why? Why would this empty space exist the widgets have all decreased in size meaning that they have retracted from their position leaving space which I would have assumed would be removed so that the widgets in the next index position underneath could shift upwards. In other terms, if the size decreases as to retract from a position then shouldn't the layout adjust its allocated space for this widget? I've never had a problem with this before... And one last thing, as an answer to your statement, could I just apply a newly constructed layout to the widgets without setting anything and it would work?

I'm sorry if I do sound a bit rude... I appreciate the help you and others on this form willingly provide, even if I am being difficult.

[SGaist]

Widgets in a layout manager are evenly distributed unless you modify their stretch factor (by default 0 IIRC). In the case of a vertical layout, if you add a stretch with a higher value at the last position you should have all your widgets pushed against one another to the top.

QVBoxLayout *layout = new QVBoxLayout(this);
layout->addWidget(widget1);
layout->addWidget(widget2);
etc.
layout->addStretch(1);

Good !

However, I'm not sure I'm following you on that one. Where did you put that resize ?

If you can't from the Topic Tools menu, then just edit the thread title and prepend [solved]
