QMainWindow with Partial Transparent Background and Custom Shape

[rmagro]

Hi Qt developers,

I wrote a simple Qt4 code to get a QMainWindow with Partial Transparent Background and Custom Shape..
Here the core of my application:

setMask((new QPixmap("logoic_big.png"))->mask());
 
	QPalette* palette = new QPalette();
	palette->setBrush(QPalette::Background,*(new QBrush(*(new QPixmap("logoic_big.png")))));
	setPalette(*palette); 	
 
	setWindowFlags(Qt::FramelessWindowHint); 	 
 	QWidget *centralWidget = new QWidget(this);
 	QGridLayout *layout = new QGridLayout();
 
 	centralWidget->setLayout(layout);
 
	QPushButton* m_showAddCommentButton = new QPushButton();
	m_showAddCommentButton->setFlat(true);
	m_showAddCommentButton->setAutoFillBackground(true);
	m_showAddCommentButton->setFixedSize(40,40);
	QPalette palett = m_showAddCommentButton->palette();
	palett.setColor(QPalette::Button,QColor(Qt::transparent));
	m_showAddCommentButton->setPalette(palett);
	m_showAddCommentButton->setIcon(QIcon("exit.png"));
	m_showAddCommentButton->setIconSize(QSize(40,40));
	m_showAddCommentButton->setToolTip("Close");
 
	layout->addWidget(m_showAddCommentButton,0,0);
 
 	setCentralWidget(centralWidget);
 
	connect(m_showAddCommentButton, SIGNAL(clicked()), this, SLOT(close()));

setMask((new QPixmap("logoic_big.png"))->mask());
	
	QPalette* palette = new QPalette();
	palette->setBrush(QPalette::Background,*(new QBrush(*(new QPixmap("logoic_big.png")))));
	setPalette(*palette); 	
	
	setWindowFlags(Qt::FramelessWindowHint); 	 
 	QWidget *centralWidget = new QWidget(this);
 	QGridLayout *layout = new QGridLayout();
 	
 	centralWidget->setLayout(layout);
 
	QPushButton* m_showAddCommentButton = new QPushButton();
	m_showAddCommentButton->setFlat(true);
	m_showAddCommentButton->setAutoFillBackground(true);
	m_showAddCommentButton->setFixedSize(40,40);
	QPalette palett = m_showAddCommentButton->palette();
	palett.setColor(QPalette::Button,QColor(Qt::transparent));
	m_showAddCommentButton->setPalette(palett);
	m_showAddCommentButton->setIcon(QIcon("exit.png"));
	m_showAddCommentButton->setIconSize(QSize(40,40));
	m_showAddCommentButton->setToolTip("Close");

	layout->addWidget(m_showAddCommentButton,0,0);

 	setCentralWidget(centralWidget);

	connect(m_showAddCommentButton, SIGNAL(clicked()), this, SLOT(close()));

To copy to clipboard, switch view to plain text mode 

My question is:
How can I put buttons in a specified positon, that I like, of my custom shape QmainWindows ?

Many thanks in advance..

Don't use layout, then you can move button where you want:

QPushButton* pb = new QPushButton( "Test Button", centralWidget );
pb->move( 200, 155 );

QPushButton* pb = new QPushButton( "Test Button", centralWidget );
pb->move( 200, 155 );

To copy to clipboard, switch view to plain text mode
