How to change the title of the window in Qt?如何在Qt中更改窗口的标题? (Both for
QDialog
and QMainWindow
.) (对于
QDialog
和QMainWindow
。)
void QWidget::setWindowTitle ( const QString & )
EDIT: If you are using QtDesigner , on the property tab, there is an editable property called windowTitle which can be found under the QWidget section.编辑:如果您使用 QtDesigner ,在属性选项卡上,有一个名为windowTitle的可编辑属性,可以在 QWidget 部分下找到。 The property tab can usually be found on the lower right part of the designer window.
通常可以在设计器窗口的右下方找到属性选项卡。
For new Qt users this is a little more confusing than it seems if you are using QT Designer and .ui
files.对于新的 Qt 用户来说,这比使用 QT Designer 和
.ui
文件时看起来更令人困惑。
Initially I tried to use ui->setWindowTitle
, but that doesn't exist.最初我尝试使用
ui->setWindowTitle
,但这并不存在。 ui
is not a QDialog
or a QMainWindow
. ui
不是QDialog
或QMainWindow
。
The owner of the ui
is the QDialog
or QMainWindow
, the .ui
just describes how to lay it out. ui
的所有者是QDialog
或QMainWindow
, .ui
只是描述如何布置它。 In that case, you would use:在这种情况下,您将使用:
this->setWindowTitle("New Title");
I hope this helps someone else.我希望这对其他人有帮助。
I know this is years later but I ran into the same problem.我知道这是几年后的事,但我遇到了同样的问题。 The solution I found was to change the window title in main.cpp.
我找到的解决方案是更改 main.cpp 中的窗口标题。 I guess once the
w.show();
我猜一旦
w.show();
is called the window title can no longer be changed.被称为窗口标题不能再更改。 In my case I just wanted the title to reflect the current directory and it works.
在我的情况下,我只希望标题反映当前目录并且它有效。
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.setWindowTitle(QDir::currentPath());
w.show();
return a.exec();
}
您还可以在 Qt 设计器中修改windowTitle属性。
system("title WhateverYouWantToNameIt");
