如何隐藏QDialog窗口的标题栏？ [英] How to hide titlebar of the QDialog window?

问题描述

我在qt应用程序中的菜单操作单击窗口上显示一个对话框，该对话框显示得很完美，但是我想隐藏其标题栏，因为它只是主窗口内的一个子窗口。

I show a dialog in my qt application on menu action click window is appearing perfectly but I want to hide its title bar as it is just a sub-window inside main window.

我尝试过：

this->setWindowFlags(Qt::Window |Qt::FramelessWindowHint);

在对话框构造函数中：

ui->setupUi(this);
this->setWindowState (Qt::WindowActive);
setWindowModality(Qt::ApplicationModal);
setAttribute (Qt::WA_DeleteOnClose);
this->setWindowFlags(Qt::Window |Qt::FramelessWindowHint) ; // 

这确实删除了标题栏，但同时也隐藏了主窗口，这对我来说是不利的

This does remove the title bar but it also hides the main window, which is bad for my application.

如何隐藏对话框标题栏而不打扰应用程序的基本主窗口？

How can I hide dialog title bar without disturbing the base main window of the application?

 QDialog *dialog(new QDialog /* this should be your dialog class youve created obviously*/));
