}如何使用
创建一个垂直栏将标题栏包起来就行。
#ifndef CDIALOG_H
#define CDIALOG_H#include QDialog
#include CTitleBar.hclass CDialog : public QDialog {Q_OBJECT
public:explicit CDialog(QString title, QWidget *parent nullptr,bool showmin false,bool showmax false, int width 400, int height 400);virtual ~CDialog();void setSubDialog(QLayout* subLayout); protected:void initUI(QString title,int width,int height,bool showmin,bool showmax);private:CTitleBar* m_titleBar;QVBoxLayout* m_layout; QLayout* m_subLayout;
};#endif // CDIALOG_H
#include CDialog.h
#include QVBoxLayoutCDialog::CDialog(QString title, QWidget *parent ,bool showmin, bool showmax, int width, int height) : QDialog(parent), m_subLayout(nullptr) {setWindowFlags(windowFlags() | Qt::FramelessWindowHint);initUI(title,width,height,showmin,showmax);
}CDialog::~CDialog() {
}void CDialog::initUI(QString title,int width,int height, bool showmin, bool showmax) {m_titleBar new CTitleBar(this,title, showmin, showmax);connect(m_titleBar, CTitleBar::closeClicked, this, CDialog::close);m_layout new QVBoxLayout(this);m_layout-addWidget(m_titleBar,0,Qt::AlignTop);m_layout-setContentsMargins(0, 0, 0, 0);m_layout-setSpacing(0);if (m_subLayout) {m_layout-addLayout(m_subLayout);}setLayout(m_layout);this-resize(width,height);setStyleSheet(QDialog{background-color:white});m_titleBar-setStyleSheet(background-color:rgb(240,240,240));
}void CDialog::setSubDialog(QLayout* subLayout) {if (subLayout ! nullptr m_layout ! nullptr) {m_subLayout subLayout;m_layout-addLayout(m_subLayout);}
}
当你继承了这个CDialog的时候就会直接出现一个标题栏和一个窗体了。
