Custom QMainWindow

beowulf

Hi guys, i'm trying to make a custom window, i can do this using this code, but i can't resize because of the fixed size, and i can't move only in the Titlebar (custom title bar), in any place i can move, how move only in the titlebar?.

MyWindow.h
@#include <QMainWindow>
#include <QLabel>
#include <QPushButton>
#include <QMouseEvent>

class MyWindow : public QMainWindow {
Q_OBJECT
private:
QLabel *label_title,*label_quit;
QPushButton *bn_exit;
QPixmap *pixmap;
QPoint m_dragPosition;

public:
MyWindow(QMainWindow *parent = 0, Qt::WindowFlags flags = 0);
protected:
void paintEvent(QPaintEvent *event);
void mouseMoveEvent(QMouseEvent *event);
void mousePressEvent(QMouseEvent *event);
};@

MyWindow.cpp
@#include "MyWindow.h"
#include <QApplication>
#include <QPainter>
#include <QLabel>

MyWindow::MyWindow(QMainWindow *parent, Qt::WindowFlags flags) : QMainWindow(parent,flags) {

resize(1024,576);
setWindowTitle("Versuch1");

//Titel
label_title = new QLabel("irgendwas",this);
label_title->setGeometry(10,10,500,40);
label_title->setStyleSheet("font-family: Arial; letter-spacing: 4px;font-weight:bold; color : white;font-size: 30px");

//Exit-Button
bn_exit = new QPushButton("[Exit]",this);
bn_exit->setGeometry(975,10,40,20);
bn_exit->setStyleSheet("QPushButton {font-family: Verdana; font-size:15px; top:0px; border: none; background-color:#101010; color:white} QPushButton:hover {color: red }");
connect(bn_exit,SIGNAL(clicked()),qApp,SLOT(quit()));

}

void MyWindow::paintEvent(QPaintEvent *event) // Painter
{
QPainter painter(this);
painter.setPen(Qt::NoPen); // deactivate Border

painter.setBrush(QBrush("#101010")); // black title and footer
painter.drawRect(0, 0, 1024, 60);

painter.setBrush(QBrush("#101010"));
painter.drawRect(0, 516, 1024, 576);
}
void MyWindow::mouseMoveEvent(QMouseEvent *event)
{
if (event->buttons() & Qt::LeftButton) {
move(event->globalPos() - m_dragPosition);
event->accept();
}
}
void MyWindow::mousePressEvent(QMouseEvent *event)
{
if (event->button() == Qt::LeftButton) {
m_dragPosition = event->globalPos() - frameGeometry().topLeft();
event->accept();
}
}@

main.cpp
@#include <QApplication>
#include "MyWindow.h"

int main(int argc, char argv[]) {
QApplication app(argc, argv);
MyWindow window = new MyWindow(0, Qt::FramelessWindowHint);
window->show();
return app.exec();
}@

when i got you right you want to move the main window with the "label_title":
@
label_title->installEventFilter(this);
...
bool MyWindow::eventFilter(QObject* watched, QEvent* event)
{
if( watched == label_title )
{
switch( event->type() )
{
case QEvent::MousePress:
{
QMouseEvent* me = static_cast<QMouseEvent*>(event);
if( me->button() == Qt::LeftButton )
{
m_MovingState = true;
m_MovingPos = me->globalPos();
}
}
break;
case QEvent::MouseMove:
{
if( m_MovingState )
{
QMouseEvent* me = static_cast<QMouseEvent*>(event);
m_State = Moving;
this->move( this->pos() + (me->globalPos() - m_MovingPos) );
m_MovingPos = me->globalPos();
}
}
break;
case QEvent::MouseRelease:
{
QMouseEvent* me = static_cast<QMouseEvent*>(event);
if( me->button() == Qt::LeftButton )
m_MovingState = false;
}
break;
}
}
}

Not tested though...but it should give you an idea..
