Hello!

Help me to delete this:

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

Dialog::Dialog(QWidget *parent) :
QDialog(parent),
ui(new Ui::Dialog),
x( 20 ),
y( 20 )
{
ui->setupUi(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()
{
QPushButton *horse1 = new QPushButton( this );
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();
}

I want to move a button by timer. But I see this trace how in the picture. How to delete this trace?

I want to move a button by timer.

Do you want to "move a button" or "move a button by timer"?

[8Observer8]

Yes, yes! Sorry for my English: move a button by timer Please, help me!

[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();
}

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!
