Enlarge Pushbutton?

[triperzonak]

hi im trying to enlarge my push button when ever the mouse points at it.

what should i do?

im trying to use "mousemoveevent" but this event happen only when the mouse was "click", i dunno y?

when you point the mouse pointer to the qpushbutton the border becomes orange and when gone back to default. i just want to do it like that, but change the size

do i need to create a custom widget for push button?

Hello, you could try to enable mouse tracking for your button. It should then receive mouseMoveEvents without a clicked button.

im sorry i forgot to say that i already set the mouse tracking of all widgets to true.. my main widgets are a groupbox textedit label and button.. but mousemoveevent stiil require "click" plus a cant get the event->pos() inside my group box even i click it..
Y?

Hi Friend,

Set MouseTracking to true. Then you can get the Mouse events.
Then you mouseMoveEvent(QMouseEvent *event);

So from event->pos(). you can get the current position of the mouse.
Then change the geometry of your QPushButton.

heres my code:
.h

#include <QMouseEvent>
#include <QMainWindow>
#include "ui_multibutton.h"
 
class multibuttonImpl : public QMainWindow, public Ui::multibutton
{
Q_OBJECT
public:
	multibuttonImpl( QWidget * parent = 0, Qt::WFlags f = 0 );
signals:
 
public slots:
	void add_item();
	void show_name();
protected:
[B]void mouseMoveEvent(QMouseEvent *);[/B]
};

#include <QMouseEvent>
#include <QMainWindow>
#include "ui_multibutton.h"

class multibuttonImpl : public QMainWindow, public Ui::multibutton
{
Q_OBJECT
public:
	multibuttonImpl( QWidget * parent = 0, Qt::WFlags f = 0 );
signals:

public slots:
	void add_item();
	void show_name();
protected:
[B]void mouseMoveEvent(QMouseEvent *);[/B]
};

		pushButton->setGeometry(QRect(600, 210, 141, 101));

	setMouseTracking(true);

	textEdit->append(mouse_pos.toString());
	
	if (pushButton->underMouse()==true )
		pushButton->setGeometry(QRect(600, 210, 141, 101));

note: i setmousetracking=true in all my widget in my .ui but "mousemoveevent" still requires "click"

note again: im using a group box

[triperzonak]

i think i found now the problem.. its in my group box, i try to change the groupbox into frame and now its working..

tnx.. but y is it like that?

[triperzonak]

weee.. i try to create dynamicaly the pushbutton and add it to frame but now its not working requires "drag click" again help...

help help help y is "mousemoveevent" not working?

[triperzonak]

now i found the answer on my question but created again another question..

after i remove the frame and put my dynamic buttons directly to the centralwidget like

pushbutton= new QPushButton(this)

pushbutton= new QPushButton(this)

To copy to clipboard, switch view to plain text mode 

it works!..

however y is it like that? if i put a button on a groupbox mouseevent inside it is not working.. if i put the buttons on a frame and dynamically create the buttons "mousemoveevent" is more like "mousepressevent" y?

until this time i have no problems but if i further improve my project i will have.. I cant put background image on my buttons alone cause i have no frame or groupbox it will affect the whole form.. hayyzzzzzz

note: just to clarify i setmousetracking on groupbox and frame as true, it is not the problem..
