No ToolTips in my application

[rambo83]

Hello,

I have searched the forum for similar questions, but did not find the solution...

I have created my GUI Framework in Qt Designer 4.5.1 and have set ToolTips (text) to some pushbuttons, but if I hold mouse above these buttons nothing appears during the execution of my application. I have seen, that it is possible to activate all ToolTips by Qt::WA_AlwaysShowToolTips. Also this does not solve the problem:

mainFrame::mainFrame(QWidget *parent)
    : QMainWindow(parent)
{
	ui.setupUi(this);
 
	this->setAttribute(Qt::WA_AlwaysShowToolTips,true);

mainFrame::mainFrame(QWidget *parent)
    : QMainWindow(parent)
{
	ui.setupUi(this);

	this->setAttribute(Qt::WA_AlwaysShowToolTips,true);

To copy to clipboard, switch view to plain text mode 

What is wrong here?

best regards,

Vitali
