How to manage QSplitter in Qt Designer
提问by zar
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?
当我按下一个按钮时，我会弹出一个对话框，用户可以在其中选择内容并在最后按“确定”。我想要这个对话框中的分隔符。左窗格将显示树，右窗格将显示其他内容。我该怎么做才对？
From Qt example itself:
从 Qt 示例本身：
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.
所以在这个例子中，splitter 是在没有任何对话框资源的情况下创建的。如果我必须以这种方式创建，那就意味着我必须在代码中创建所有控件，而不是 Qt Creator。
What is the right way to do this when I need other controls on the screen?
当我需要屏幕上的其他控件时，正确的方法是什么？

You can simply create splitter containing items in Qt Designer :
您可以简单地在 Qt Designer 中创建包含项目的拆分器：
First place your widgets on your dialog or widget in designer (They should not be in a layout)
Select the widgets that you want to be in a splitter (By holding CTL and clicking on them)
Right click on a selected widget and from Layoutmenu select Lay Out Horizontally in Splitteror Lay Out Vertically in Splitter.
Now apply a grid layout to the dialog and everything should be OK. You would see something like this in Object Inspector View :
首先将您的小部件放在您的对话框或设计器中的小部件上（它们不应该在布局中）
选择要在拆分器中的小部件（按住 CTL 并单击它们）
右键单击选定的小部件，然后从布局菜单中选择在拆分器中水平布局或在拆分器中垂直布局。
现在将网格布局应用于对话框，一切都应该没问题。您会在 Object Inspector View 中看到类似的内容：

You can still create your controls in a .ui file using Qt Designer (integrated in Qt Creator). Within Qt Designer, add a QWidgetobject to your dialog. Then, from QDialog derived class you'll write, directly in your constructor, create your QSplitter using the QWidgetobject as a parent.
您仍然可以使用 Qt Designer（集成在 Qt Creator 中）在 .ui 文件中创建控件。在 Qt Designer 中，QWidget向对话框添加一个对象。然后，从 QDialog 派生类，您将直接在构造函数中编写，使用该QWidget对象作为父对象创建 QSplitter 。
This way, you can create all but the splitter object from Qt Designer.
这样，您可以从 Qt Designer 创建除拆分器对象之外的所有对象。
I think it's also possible to create the QSplitter(as you can create a QButton, QCheckBox...) item directly from Qt Designer.
我认为也可以直接从 Qt Designer创建QSplitter（因为你可以创建一个QButton，QCheckBox...）项目。
