如何设置QMainWindow作为模态一？ [英] How to set QMainWindow as the modal one?

问题描述

我使用QMainWindow为我的项目的GUI开发。我遇到的一个问题是阻止所有其他可见窗口获取输入，而一个正在操作。

我如何声明一个特定的窗口为模态？

我尝试使用 QWidget :: setWindowMOdality（）。

  #include< QApplication> 
 #include< QMainWindow> 
 #include< QPushButton> 
 
 
 
 
 int main（int argc，char ** argv）{
 
 
 QApplication a（argc，argv ）; 
 
 
 QMainWindow * w1 = new QMainWindow（）; 
 w1-> resize（500,800）; 
 w1-> move（100,50）; 
 w1-> show（）; 
 
 
 QMainWindow * w2 = new QMainWindow（）; 
 w2-> resize（800,500）; 
 w2-> move（50,50）; 
 w2-> show（）; 
 
 w2-> setWindowModality（Qt :: ApplicationModal）; 
 
 
 return a.exec（）; 
 
} 
  

解决方案

  w2-> setWindowModality（Qt :: ApplicationModal） 
 w2-> show（）; 
  

也可以使用QWidget并建立工具栏，菜单栏和状态栏。

I am using QMainWindow for GUI development of my project..One problem I am Stuck with is blocking all other visible windows from getting input, while one is in operation.

I can not use QDialog.Because rich features of QMainWindow is required.

How can I declare a particular window as modal?

I tried with QWidget::setWindowMOdality().

Here is a demo program, what I tried but it didnt work.

#include <QApplication>
#include <QMainWindow>
#include <QPushButton>




int main(int argc, char **argv){


QApplication a(argc, argv);


    QMainWindow *w1 = new QMainWindow();
    w1->resize(500,800);
    w1->move(100,50);
    w1->show();


    QMainWindow *w2= new QMainWindow();
    w2->resize(800,500);
    w2->move(50,50);
    w2->show();

    w2->setWindowModality(Qt::ApplicationModal);


    return a.exec();

}

解决方案

Try setting the modal flag first, then show the widget.

w2->setWindowModality(Qt::ApplicationModal);
w2->show();

Also you could use QWidget and build the toolbar, menu bar and status bar.
