停靠在主窗口右侧时，QDockWidget大小错误 [英] QDockWidget sized wrong when docked on right side of Main Window

问题描述

我是Qt的新手，我正在尝试创建一个停靠在窗口右侧的DockWidget.我为扩展坞设置了最大和最小宽度(如下面的代码所示).如果使用Qt::LeftDockWidgetArea添加了停靠小部件，则可以使用该功能，但是如果使用Qt::RightDockWidgetArea添加了停靠小部件，则该停靠将被填充"到窗口的中央，如下所示:

I am new to Qt and I am trying to create a DockWidget that docks on the right of the window. I set a maximum and minimum width for the dock (as you will see in the code below). This works if the dock widget is added with Qt::LeftDockWidgetArea, but when it is added with Qt::RightDockWidgetArea, The dock is "padded" out to the center of the window, like this:

我可能没有以正确的方式调整码头的尺寸..这是此窗口的代码:

I am probably not sizing the dock in the correct way.. Here is the code for this window:

int main(int argv, char** args)
{
    QApplication app(argv, args);
    QMainWindow window;
    QDesktopWidget* desktop = QApplication::desktop();
    //Docks
    QDockWidget* propertyDock = new QDockWidget("",&window);
    QWidget* propertyDockContents = new QWidget;

    //This sets the window in the center of the screen.
    int wWidth = 800; int wHeight = 600;
    window.setGeometry(QRect( (desktop->width()-wWidth)/2 , (desktop->height()-wHeight)/2 ,wWidth,wHeight));

    propertyDock->setAllowedAreas(Qt::RightDockWidgetArea);
    propertyDockContents->setMaximumWidth(200);
    propertyDockContents->setMinimumWidth(20);

    propertyDock->setWidget(propertyDockContents);
    window.addDockWidget(Qt::RightDockWidgetArea,propertyDock);

    window.show();

    return app.exec();
}

是否有正确"的方法来做到这一点?

Is there a "correct" way to do this?

推荐答案

如文档中所述:

注意:不支持创建没有中央窗口小部件的主窗口.即使它只是一个占位符，也必须有一个中央窗口小部件.

Note: Creating a main window without a central widget is not supported. You must have a central widget even if it is just a placeholder.
