如何设置QMainWindow的Windows任务栏标题？(How to set Windows taskbar title of a QMainWindow?)

如何设置QMainWindow的Windows任务栏标题？(How to set Windows taskbar title of a QMainWindow?)

出于好奇：我目前正在Windows 7上开发一个Qt应用程序。我想设置窗口标题以显示在任务栏中。 setWindowTitle不适用，因为我的UI是QMainWindow ，而不是QWidget 。

我有一个标题的QString ，但我无法设置它。 我在Qt Designer中设置了QMainWindow标题但这是静态的。 我所达到的只是：

MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent) { // .... QApplication::setApplicationDisplayName(qAppTitle); parent->setWindowTitle(qAppTitle); // ... }

这会将我的任务栏中的窗口标题变为：

[来自Qt Designer的标题] - [qAppTitle变量]

吮吸。

想法？

Out of curiosity: I am currently developing a Qt application on Windows 7. I want to set the window title to display in the taskbar. setWindowTitle is not applicable as my UI is a QMainWindow, not a QWidget.

I have a QString with the title, but I can't set it. I set the QMainWindow title in the Qt Designer but that's static. All I had reached is this:

MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent) { // .... QApplication::setApplicationDisplayName(qAppTitle); parent->setWindowTitle(qAppTitle); // ... }

This turns the window title in my taskbar into:

[title from Qt Designer] - [qAppTitle variable]

Sucks.

Ideas?

QMainWindow有一个与QWidget相同的setWindowTitle（因为它是一个），请看这个问题：

如何设置QMainWindow标题

因此解决方案是：

MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent) { setWindowTitle("Hello world"); }

也

"QMainWindow Class The QMainWindow class provides a main application window. More... #include <QMainWindow> Inherits: QWidget."

QMainWindow has a setWindowTitle the same as QWidget (because it is one), see this question:

How to set QMainWindow title

Thus the solution is:

MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent) { setWindowTitle("Hello world"); }
