Adding widgets dynamically to layout, causes to them to be misplaced
-
Well, one thing I know is that the custom widget's size constraints had to set to a minimum. It used quite a lot of space so it was centered on top of another layout/widget. Now it's loaded where it should, but after it's deletion there still is a void space.
That's the code:
void QtDice::enableUserWidget() { userwidget = new UserWidget(this); m_ui->gridLayout_Widget->addWidget(userwidget); } void QtDice::deleteUserWidget() { m_ui->gridLayout_Widget->removeWidget(userwidget); userwidget->setParent(nullptr); delete userwidget; }Other suspects could be the main form (i.e. the QtDice qmainwindow) and it's size policies or the vertical spacer. I tried almost every combination and I am out of ideas.
Do you use TakeAt to remove from layout ?
Ebook Mastering Qt5, suggested the
QLayout::removeWidget, so...@Petross404_Petros-S
Oh, yes, removeWidget seems better in this case and you do change parent.
Hmm, i would also suspect spacer.
Sorry i cant spot it. All seems pretty dandy with code shown. -

For the moment I just create unconditionally the
userwidgetand all that clicking the checkbox does, is to enable or disable it. But it's always visible.It's not what I like, but it gives the functionality I am working on without an ugly ui. Until I find and post what the missing part of this puzzle is, I will leave this as UNSOLVED.

What about hiding it while the condition to use it are not met ?

Why use an empty QVBoxLayout as a placeholder for your userwidget? Why not just simply put your userwidget into the layout of your Mainwindow?
I guess you are using another QVBoxLayout as the Layout of your Mainwindow so you could use:
m_ui->yourmainlayoutname->insertWidget( 1, userwidget);On a sidenote: You don't need to put your textlabel-placeholder for your dice into a QGridLayout too, just put it into your Mainwindow-Layout and maybe set stretch-factors to your likeing.

So, at first the window is at it's most minimum size. After enabling the widget it resizes a little, but after closing the widget again, the window doesn't resize back but rather the
QLabelthat shows the red dice expands.I can't find some way to alter this. I have tried every combination for
QLabelabout it'sSizePolicybut nothing changed. -

This is the default behavior of the layout-system here but you can get what you want by readjusting the size of your MainWindow after deleting the userwidget. In your case you have two QWidgets involved: your QtDice-MainWindow and its centralWidget(). So you need to adjust both of them!Try adding
centralWidget()->adjustSize(); adjustSize();after removing the userwidget.

@MCam Thank you, I was using plain
adjustSize()that's why it didn't resize. Although there is problem that remains even when resizing both layouts :After unmaximising the window,
adjustSizegives this result. I will mark the thread as solved because I can make the window to not be able to get maximized, but for completeness shake it would be nice if this result could be avoided.Either way, you saved my day and I thank you very much for that :)
