wait copy picture then show it

[raphaelf]

Hi everybody

QT 4.1.3 WINXP MINGW

I have a functionm that copy a picture from a server local and show it.

My function work, but sometimes the copy process is not fast and i cant see the picture.

I am searching a solution for my function, that i wait until the picture is complete copied local, and then show it.

Have somebody a idea?

void MainWindow::showPicure()
{
	ui.label->clear();
	QString src =  (ui.listView->currentItem() )->text( 4 );
	QMessageBox::information(this, "src", src);
	QFileInfo file(src);
  	if(file.isReadable() == true)
  		{
 
	  		Q3UrlOperator *op = new Q3UrlOperator();                       
	  		QString temp_picture = "c:/temp/temp_album.jpg";  
			op->copy(src, temp_picture, false, false);     
			QMessageBox::information(this, "wait", "wait");   
			ui.label->setPixmap(QPixmap(temp_picture));
			ui.picture_lb->setText("");
  		}
  		else
  		{
	  		ui.picture_lb->setText("No Picture");
	  		ui.label->clear();
  		}
}

void MainWindow::showPicure()
{
	ui.label->clear();
	QString src =  (ui.listView->currentItem() )->text( 4 );
	QMessageBox::information(this, "src", src);
	QFileInfo file(src);
  	if(file.isReadable() == true)
  		{
	  		
	  		Q3UrlOperator *op = new Q3UrlOperator();                       
	  		QString temp_picture = "c:/temp/temp_album.jpg";  
			op->copy(src, temp_picture, false, false);     
			QMessageBox::information(this, "wait", "wait");   
			ui.label->setPixmap(QPixmap(temp_picture));
			ui.picture_lb->setText("");
  		}
  		else
  		{
	  		ui.picture_lb->setText("No Picture");
	  		ui.label->clear();
  		}
}

To copy to clipboard, switch view to plain text mode
