Handling mouseevent in Qstatusbar .

 

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 ,

  1. QLabel *cpyrightlbl= new QLabel();
  2.  ui.statusBar->addWidget(cpyrightlbl);
  3.  cpyrightlbl->setText("Demo Message");
  4.  cpyrightlbl->setWindowFlags( Qt::FramelessWindowHint );
  5.  cpyrightlbl->setStyleSheet("border: 3px");
  6.  cpyrightlbl->setFixedWidth(frameGeometry().width());
  7.              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.

check this [qt-project.org]

  5.  
  6. class MsgDisplay : public QLabel
  7. {
  8.  Q_OBJECT
  9. public:
  10.  MsgDisplay(QWidget *parent = 0);
  11.  ~MsgDisplay();
  12.  void setMessage(QString str);
  13. protected:
  14.  virtual void mousePressEvent(QMouseEvent * event);
  15. };
  16.  
  17. #endif // MSGDISPLAY_H
  18.  
  19. inside display.cpp
  20.  
  21. #include "MsgDisplay.h"
  22.  
  23. MsgDisplay::MsgDisplay(QWidget *parent)
  24.  : QLabel(parent)
  25. {
  26.  
  27. }

  55. }

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?
