Qt::Popup with titlebar

[keyur259]

Hi,

I have a subclass of QWidget. And I have set windowFlags to Qt::Popup in the constructor. But when popup widget is displayed, it comes without titlebar. I have also tried Qt::Popup | Qt::WindowTitleHint. But it's still displayed without titlebar.

How can I get popup with title bar?

Please reply.

Thanks & Regards,
Keyur Shah

With Qt::Popup you wont get the title bar.
Dont set any flags, and you will get the widget with a title bar. You can also use QDialog , or QWidget with Qt::Tool flag set,, whatever suits you.

Thanks for your reply.

Oh... But none of other flags gives me what i wants.
QDialog are providing only application specific functionaliy.

I want my widget to close if user clicks outside the widget or better outside the application too.

So how can I get such things without using Qt::Popup flag?

[aamer4yu]

Well, if thats the case, I can think only of the following for now -
Draw the title bar yourself in the paintevent of your widget. And you can have the Qt::Popup flag set on your widget too

Is there any method using which I can draw titlebar of widget by myself?

[aamer4yu]

QStylePainter::drawComplexControl(QStyle::CC_TitleBar,option);

[keyur259]

Still it is diaplyed without titlebar.

I have written following code in paintEvent

QStylePainter painter( this );
QStyleOptionTitleBar option;
painter.drawComplexControl( QStyle::CC_TitleBar, option );

Please let me know if I am missing something.

[aamer4yu]

try setting option.initFrom(this);
But I doubt if QStyle will permit you draw a title bar on a Qt::Popup widget.

You can try setting the QStyleOptionTitleBar::titleBarFlags and see if draws.

How to set QStyleOptionTitleBar::titleBarFlags???

Do you mean set the widget->setWindowFlags(Qt::WindowTitleHint) ?

[faldzip]

What is the exact functionality you want and get with Qt::Popup and you can't get with other flags?

[keyur259]

With Qt::Popup, If I click anywhere including outside application, only the popup will be dismissed and no other window has any effect.

I got it working by -

class PopupWithTitle : public QWidget
{
public:
	PopupWithTitle(QWidget* parent =0);
	~PopupWithTitle();
protected:
	void paintEvent ( QPaintEvent * event ) ;
 
};
 
PopupWithTitle::PopupWithTitle(QWidget* parent) : QWidget(parent)
{
	setWindowFlags( Qt::Popup);
	setFixedSize(300,200);
}
 
PopupWithTitle::~PopupWithTitle()
{
 
}
 
void PopupWithTitle::paintEvent ( QPaintEvent * event ) 
{
	QWidget::paintEvent(event);
 
	QStylePainter stylePainter(this);
	QStyleOptionTitleBar option;
	option.initFrom(this);
	option.text = "Popup title";
	option.rect = rect();
	option.rect.setHeight(20);
	stylePainter.drawComplexControl(QStyle::CC_TitleBar,option);
}

class PopupWithTitle : public QWidget
{
public:
	PopupWithTitle(QWidget* parent =0);
	~PopupWithTitle();
protected:
	void paintEvent ( QPaintEvent * event ) ;

};

PopupWithTitle::PopupWithTitle(QWidget* parent) : QWidget(parent)
{
	setWindowFlags( Qt::Popup);
	setFixedSize(300,200);
}

PopupWithTitle::~PopupWithTitle()
{

}

void PopupWithTitle::paintEvent ( QPaintEvent * event ) 
{
	QWidget::paintEvent(event);

	QStylePainter stylePainter(this);
	QStyleOptionTitleBar option;
	option.initFrom(this);
	option.text = "Popup title";
	option.rect = rect();
	option.rect.setHeight(20);
	stylePainter.drawComplexControl(QStyle::CC_TitleBar,option);
}

But yes, the window doesnt move, if you need that, you need to implement yourself

Thanks.. I have got popup with titlebar.

I will try to implement dragging & coloring the titlebar with close button.

And will let you know if will get any problems.

If someone already know please reply.

Hint :
QStylePainter::drawItemPixmap
QStyle::standardIcon and QStyle::SP_TitleBarCloseButton

mousePressEvent

Hi, I have got titlebar & close button. And also able to drag it now using coding.

But I am unable to get text in titlebar. Shall we have to add control for it in paintEvent?

And color of the titlebar is not the same as other windows have. How can I get the general window titlebar color & set it for cuurrent titlebar?

[aamer4yu]

Did you try the code I posted ? I could get text in the title bar.

Anyways the functionalities you are adding, I guess it would be better to simply use a modal QDialog instead of so many turnarounds.

[keyur259]

I have used the code that you have posted using which I have got the titlebar without text. Then also I wil re-check.

The problem with modal dialog is It is only application specific modal.

Wanna share your code how to add close button ? And maybe drag function if you finish it.

For Close Button, Title Bar With Text & PopUp with Frame

void CustomPopUp::paintEvent( QPaintEvent* event )
{
    QWidget::paintEvent( event );
 
    QStylePainter painter( this );
    QPalette tPalette = palette();
    tPalette.setColor( QPalette::WindowText, QColor( Qt::white ) );
 
    QStyleOptionTitleBar titleOption;
    titleOption.initFrom( this );
    titleOption.text = "Custom PopUp";
    titleOption.rect = rect();
    titleOption.rect.setHeight( 23 );
    titleOption.titleBarState = (int)Qt::WindowActive | ~Qt::WindowMinimized;
    painter.drawComplexControl( QStyle::CC_TitleBar, titleOption );
 
    QStyleOptionFrame frameOption;
    frameOption.initFrom( this );
    frameOption.rect = QRect( rect().x(), rect().y() + 23, rect().width(), rect().height() - 23 );
    painter.drawPrimitive( QStyle::PE_Frame, frameOption );
 
    QIcon icon = style()->standardIcon( QStyle::SP_DialogCloseButton );
    QRect r = QRect( 0, 0, rect().width() - 5, 23 );
    painter.drawItemPixmap( r, (int)Qt::AlignRight | Qt::AlignVCenter, icon.pixmap( 19, 19 ) );
 
    r = QRect( 0, 0, rect().width(), 23 );
    QFont f = painter.font();
    f.setBold( true );
    painter.setFont( f );
    painter.drawItemText(  r, (int)Qt::AlignHCenter | Qt::AlignVCenter, tPalette, true, "Custom PopUp", QPalette::WindowText );
}

void CustomPopUp::paintEvent( QPaintEvent* event )
{
    QWidget::paintEvent( event );

    QStylePainter painter( this );
    QPalette tPalette = palette();
    tPalette.setColor( QPalette::WindowText, QColor( Qt::white ) );

    QStyleOptionTitleBar titleOption;
    titleOption.initFrom( this );
    titleOption.text = "Custom PopUp";
    titleOption.rect = rect();
    titleOption.rect.setHeight( 23 );
    titleOption.titleBarState = (int)Qt::WindowActive | ~Qt::WindowMinimized;
    painter.drawComplexControl( QStyle::CC_TitleBar, titleOption );

    QStyleOptionFrame frameOption;
    frameOption.initFrom( this );
    frameOption.rect = QRect( rect().x(), rect().y() + 23, rect().width(), rect().height() - 23 );
    painter.drawPrimitive( QStyle::PE_Frame, frameOption );

    QIcon icon = style()->standardIcon( QStyle::SP_DialogCloseButton );
    QRect r = QRect( 0, 0, rect().width() - 5, 23 );
    painter.drawItemPixmap( r, (int)Qt::AlignRight | Qt::AlignVCenter, icon.pixmap( 19, 19 ) );

    r = QRect( 0, 0, rect().width(), 23 );
    QFont f = painter.font();
    f.setBold( true );
    painter.setFont( f );
    painter.drawItemText(  r, (int)Qt::AlignHCenter | Qt::AlignVCenter, tPalette, true, "Custom PopUp", QPalette::WindowText );
}
