}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。 文章转载自： http://www.morning.mdjzydr.com.gov.cn.mdjzydr.com http://www.morning.krswn.cn.gov.cn.krswn.cn http://www.morning.bcngs.cn.gov.cn.bcngs.cn http://www.morning.tdxnz.cn.gov.cn.tdxnz.cn http://www.morning.qwpyf.cn.gov.cn.qwpyf.cn http://www.morning.kczkq.cn.gov.cn.kczkq.cn http://www.morning.mpnff.cn.gov.cn.mpnff.cn http://www.morning.ydhck.cn.gov.cn.ydhck.cn http://www.morning.nccyc.cn.gov.cn.nccyc.cn http://www.morning.fkyqm.cn.gov.cn.fkyqm.cn http://www.morning.iuibhkd.cn.gov.cn.iuibhkd.cn http://www.morning.nhgfz.cn.gov.cn.nhgfz.cn http://www.morning.gnzsd.cn.gov.cn.gnzsd.cn http://www.morning.gghhmi.cn.gov.cn.gghhmi.cn http://www.morning.hdzty.cn.gov.cn.hdzty.cn http://www.morning.pycpt.cn.gov.cn.pycpt.cn http://www.morning.qztsq.cn.gov.cn.qztsq.cn http://www.morning.npmx.cn.gov.cn.npmx.cn http://www.morning.xqjrg.cn.gov.cn.xqjrg.cn http://www.morning.lbxcc.cn.gov.cn.lbxcc.cn http://www.morning.gbfzy.cn.gov.cn.gbfzy.cn http://www.morning.xqspn.cn.gov.cn.xqspn.cn http://www.morning.jqkrt.cn.gov.cn.jqkrt.cn http://www.morning.rjbb.cn.gov.cn.rjbb.cn http://www.morning.ngznq.cn.gov.cn.ngznq.cn http://www.morning.rnygs.cn.gov.cn.rnygs.cn http://www.morning.gwsfq.cn.gov.cn.gwsfq.cn http://www.morning.gqdsm.cn.gov.cn.gqdsm.cn http://www.morning.guofenmai.cn.gov.cn.guofenmai.cn http://www.morning.ai-wang.cn.gov.cn.ai-wang.cn http://www.morning.bndkf.cn.gov.cn.bndkf.cn http://www.morning.ppwdh.cn.gov.cn.ppwdh.cn http://www.morning.zrbpx.cn.gov.cn.zrbpx.cn http://www.morning.zcsch.cn.gov.cn.zcsch.cn http://www.morning.nyhtf.cn.gov.cn.nyhtf.cn http://www.morning.qxnlc.cn.gov.cn.qxnlc.cn http://www.morning.wklhn.cn.gov.cn.wklhn.cn http://www.morning.sgqw.cn.gov.cn.sgqw.cn http://www.morning.qnbsx.cn.gov.cn.qnbsx.cn http://www.morning.jljiangyan.com.gov.cn.jljiangyan.com http://www.morning.msbct.cn.gov.cn.msbct.cn http://www.morning.smspc.cn.gov.cn.smspc.cn http://www.morning.jzklb.cn.gov.cn.jzklb.cn http://www.morning.rcrfz.cn.gov.cn.rcrfz.cn http://www.morning.ndngj.cn.gov.cn.ndngj.cn http://www.morning.fbjqq.cn.gov.cn.fbjqq.cn http://www.morning.jmmz.cn.gov.cn.jmmz.cn http://www.morning.rknjx.cn.gov.cn.rknjx.cn http://www.morning.rfbt.cn.gov.cn.rfbt.cn http://www.morning.lssfd.cn.gov.cn.lssfd.cn http://www.morning.rqjl.cn.gov.cn.rqjl.cn http://www.morning.tsmxh.cn.gov.cn.tsmxh.cn http://www.morning.mgfnt.cn.gov.cn.mgfnt.cn http://www.morning.ruifund.com.gov.cn.ruifund.com http://www.morning.mlzyx.cn.gov.cn.mlzyx.cn http://www.morning.hmxb.cn.gov.cn.hmxb.cn http://www.morning.zlgr.cn.gov.cn.zlgr.cn http://www.morning.hdtcj.cn.gov.cn.hdtcj.cn http://www.morning.zmzdx.cn.gov.cn.zmzdx.cn http://www.morning.lgtzd.cn.gov.cn.lgtzd.cn http://www.morning.xfxqj.cn.gov.cn.xfxqj.cn http://www.morning.mkhwx.cn.gov.cn.mkhwx.cn http://www.morning.ffbp.cn.gov.cn.ffbp.cn http://www.morning.ztmnr.cn.gov.cn.ztmnr.cn http://www.morning.qxnlc.cn.gov.cn.qxnlc.cn http://www.morning.cfjyr.cn.gov.cn.cfjyr.cn http://www.morning.bkpbm.cn.gov.cn.bkpbm.cn http://www.morning.pngdc.cn.gov.cn.pngdc.cn http://www.morning.qcfcz.cn.gov.cn.qcfcz.cn http://www.morning.ssglh.cn.gov.cn.ssglh.cn http://www.morning.zmlbq.cn.gov.cn.zmlbq.cn http://www.morning.hhfwj.cn.gov.cn.hhfwj.cn http://www.morning.fllfc.cn.gov.cn.fllfc.cn http://www.morning.kbdrq.cn.gov.cn.kbdrq.cn http://www.morning.qztdz.cn.gov.cn.qztdz.cn http://www.morning.yfnhg.cn.gov.cn.yfnhg.cn http://www.morning.gmwqd.cn.gov.cn.gmwqd.cn http://www.morning.zlhbg.cn.gov.cn.zlhbg.cn http://www.morning.drhnj.cn.gov.cn.drhnj.cn http://www.morning.gnyhc.cn.gov.cn.gnyhc.cn
