  • 0

pretty new to using Qt. I have a custom widget that i need to have recieving button presses, then from that button press finding the position of the mouse on the widget.
Unfortunately, currently the mousePressEvent(QMouseEvent *me) doesn’t seem to be working correctly.
So i’m wondering what exactly i’m doing wrong, code below;

Header File:

#ifndef TILESHEETPANE_H
#define TILESHEETPANE_H

#include <QWidget>
#include "global.h"

class tileSheetPane : public QWidget
{
   Q_OBJECT

 public:
     tileSheetPane(int scnWidth, Global *global, QWidget *parent);

 protected:
     void mousePressEvent(QMouseEvent *me);
     void paintEvent(QPaintEvent *);

 private:
     Global *tempGlobal;
     QPoint cursorPos;
     int tileSheetPaneWidth, tileSheetPaneHeight, renderOffsetY;
 };

 #endif // TILESHEETPANE_H

Src File:

   #include <QPainter>
   #include <QMouseEvent>
   #include "tilesheetpane.h"

   //Constructor & Paint Event .. 

   void tileSheetPane::mousePressEvent(QMouseEvent *me)
   {
        cursorPos = me->pos();
   }

CursorPos’s values just say at their initialized 0. So any help would be greatly appreciated :), as i said, pretty new to using QT only started probably 2 days ago so i’m still trying to figure out things :D.

Edit;
So after trying out some of the suggestions in the comments, nothing seems to be working. I do indeed have setMouseTracking(true) but still nothing. I inserted a qDebug call into the function as suggested and it seems that the mousePressEvent never gets called. 

 void tileSheetPane::mousePressEvent(QMouseEvent *me)
 {
     cursorPos = me->pos();

     //These Never Show Up!
     qDebug() << me->pos().x();
     qDebug() << me->pos().y();
 }

Something perhaps is blocking or stopping this being called but im not sure what it could be?

    So i just couldn’t get the mouse clicking working, so after doing some searching on google, i eventually found the following video;

    As my widget is rather small anyway, i basically just re-did the entire thing. But it was worth it.
    Essentially i deleted my old files, created a Qt Designer Form, added in a new widget into my mainWindow.ui file, promoted it to use “tileSheetPane” and that’s it. Works perfectly now :D.
