C++ 我想在qt中创建一个自定义标题栏
我想在qt中创建一个自定义标题栏 所以我查阅了一些例子,并遵循它们。 下面是应用该示例的代码 小部件头文件:C++ 我想在qt中创建一个自定义标题栏,c++,qt,qwidget,C++,Qt,Qwidget,我想在qt中创建一个自定义标题栏 所以我查阅了一些例子,并遵循它们。 下面是应用该示例的代码 小部件头文件: #include <QWidget> #include <QMouseEvent> class KcWdTitlebar :public QWidget { private: QWidget *m_parent; QPoint m_pCursor; public: KcWdTitlebar( QWidget *parent) ; pr

当我运行这个代码时,
单击并拖动KcWdTitle部分将导致主窗口跟随我单击的点
我应该修复代码的哪些部分
我希望每个人都能理解我的英语。您需要更改
mousePressEvent()
以减去主窗口的几何图形,而不是标题栏的几何图形
更改:
m_pCursor = event->globalPos() - geometry().topLeft();
为此:
m_pCursor = event->globalPos() - m_parent->geometry().topLeft();
尝试更改:void KcWdTitlebar::MousePresseEvent(QMouseEvent*事件)
和void KcWdTitlebar::MouseEvent(QMouseEvent*事件)
并查看行为中是否有更改。如果是这样的话,那么这就是你应该改变的部分。Ui::mainwindow的完整定义在哪里?@DavidGrayson Ui::mainwindow中没有太多内容。我刚刚在框架顶部添加了KcWdTitlebar。
