How to manage QSplitter in Qt Designer

When I press a button, I bring up a dialog where user select things and press 'Ok' at the end. I want a splitter in this dialog. Left pane will show tree and right will show something else. How do I do that right?

From Qt example itself:

 QSplitter *splitter = new QSplitter(parent);
 QListView *listview = new QListView;
 QTreeView *treeview = new QTreeView;
 QTextEdit *textedit = new QTextEdit;
 splitter->addWidget(listview);
 splitter->addWidget(treeview);
 splitter->addWidget(textedit);

So in this example, splitter is created without any dialog resource. If I have to create this way, that would mean I have to create all my controls in the code as well rather than Qt Creator.

What is the right way to do this when I need other controls on the screen?

Solution

  • You can simply create splitter containing items in Qt Designer :

    1. First place your widgets on your dialog or widget in designer (They should not be in a layout)

    2. Select the widgets that you want to be in a splitter (By holding CTL and clicking on them)

    3. Right click on a selected widget and from Layout menu select Lay Out Horizontally in Splitter or Lay Out Vertically in Splitter.

    4. Now apply a grid layout to the dialog and everything should be OK. You would see something like this in Object Inspector View :
