Handling mouseevent in Qstatusbar .

BibekKumar

In my statusbar , i have added one Qlabel inside which i am displaying some message . Now what i want is when i click on that Qlabel(present inside the Qstatusbar ) , the message should disappear ..

I have added the label inside statusbar as follows ,

       @QLabel *cpyrightlbl= new QLabel();

ui.statusBar->addWidget(cpyrightlbl);
cpyrightlbl->setText("Demo Message");
cpyrightlbl->setWindowFlags( Qt::FramelessWindowHint );
cpyrightlbl->setStyleSheet("border: 3px");
cpyrightlbl->setFixedWidth(frameGeometry().width());
cpyrightlbl->show();@

Why do you want to use a mouseClick on the status bar message.. You can also dispay the message for a particular time interval and it will disappear after timeout.

Actually the requirement is unless the user clcik on that label , the message shall be displayed .

Subclass QLabel and reimplement mousePressEvent().

i have done as u said above , but it has no impact ..

Here i am mentioning my code

inside display.h

@#ifndef MSGDISPLAY_H
#define MSGDISPLAY_H

#include <QLabel>

class MsgDisplay : public QLabel
{
Q_OBJECT
public:
MsgDisplay(QWidget *parent = 0);
~MsgDisplay();
void setMessage(QString str);
protected:
virtual void mousePressEvent(QMouseEvent * event);
};

#endif // MSGDISPLAY_H

inside display.cpp

#include "MsgDisplay.h"

MsgDisplay::MsgDisplay(QWidget *parent)
: QLabel(parent)
{

}
void MsgDisplay::setMessage(QString str)
{
setText("<font color='Blue'>Demo Message<font>");
QFont font;
font.setPointSize(10);
font.setBold(true);
setFont(font);

}
MsgDisplay::~MsgDisplay()
{

}
void MsgDisplay::mousePressEvent(QMouseEvent * event)
{
hide();
}

inside Myclass.cpp

#include display.h

void Myclass::Label()
{
MsgDisplay *statusLabel = new MsgDisplay();
ui.statusBar->addWidget(statusLabel);
statusLabel->setMessage(QString("hi"));
}@

The code you've posted should work as expected (at least when it comes to the requested functionality). Can you provide a small, compilable example which reproduces the problem?

I got the solution for the above one ..
Now i am running through one more problem i.e when i minimize my main application window the status bar message is getting truncated . Is there any way to resolve this issue ? I mean to say the same message shall be displayed without any trucation during minimizing and maximizing .

How do you imagine to display anything on a minimized application window?
