Moving of Button

[wysota]

That's bad... If you wanted to just animate a button, that would be very easy. But if you have to do it "by timer" then I'm afraid you have some weird problem in your code you will have to fix. That might have to do something with the fact you are creating a new button each time the slot is called.

Thank you very much! It works normally now:

#include "Dialog.h"
#include "ui_Dialog.h"
 
Dialog::Dialog(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::Dialog),
    x( 20 ),
    y( 20 )
{
    ui->setupUi(this);
 
    horse1 = new QPushButton( this );
 
    connect( &m_timer, SIGNAL( timeout() ),
             this, SLOT( slotUpdate() ) );
    m_timer.start( 50 );
    //this->setStyleSheet( "background-color: rgb(177, 177, 177);" "color: black;" );
}
 
Dialog::~Dialog()
{
    delete ui;
}
 
void Dialog::slotUpdate()
{
 
    horse1->setGeometry( 20+x, 20+y, 50, 50 );
    //horse1->setStyleSheet("background-color: rgb(177, 177, 177);" "color: black;");
 
    //m_horses.push_back( horse1 );
 
    horse1->show();
    ++x;
    ++y;
    //this->setStyleSheet( "background-color: rgb(177, 177, 177);" "color: black;" );
    update();
}

#include "Dialog.h"
#include "ui_Dialog.h"

Dialog::Dialog(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::Dialog),
    x( 20 ),
    y( 20 )
{
    ui->setupUi(this);

    horse1 = new QPushButton( this );

    connect( &m_timer, SIGNAL( timeout() ),
             this, SLOT( slotUpdate() ) );
    m_timer.start( 50 );
    //this->setStyleSheet( "background-color: rgb(177, 177, 177);" "color: black;" );
}

Dialog::~Dialog()
{
    delete ui;
}

void Dialog::slotUpdate()
{

    horse1->setGeometry( 20+x, 20+y, 50, 50 );
    //horse1->setStyleSheet("background-color: rgb(177, 177, 177);" "color: black;");

    //m_horses.push_back( horse1 );

    horse1->show();
    ++x;
    ++y;
    //this->setStyleSheet( "background-color: rgb(177, 177, 177);" "color: black;" );
    update();
}

Still, if you decide that maybe you don't have to do it by using a timer, you might have a look at QPropertyAnimation.

Ok! Thank you!
