KPassivePopup Class Reference

from PyKDE4.kdeui import *

Inherits: QFrame → QWidget → QObject

Detailed Description

A dialog-like popup that displays messages without interrupting the user.

The simplest uses of KPassivePopup are by using the various message() static methods. The position the popup appears at depends on the type of the parent window:

Normal Windows: The popup is placed adjacent to the icon of the window.

System Tray Windows: The popup is placed adjact to the system tray window itself.

Skip Taskbar Windows: The popup is placed adjact to the window

itself if it is visible, and at the edge of the desktop otherwise.

You also have the option of calling show with a QPoint as a parameter that removes the automatic placing of KPassivePopup and shows it in the point you want.

The most basic use of KPassivePopup displays a popup containing a piece of text:

    KPassivePopup.message( "This is the message", this );

We can create popups with titles and icons too, as this example shows:

    QPixmap px;
    px.load( "hi32-app-logtracker.png" );
    KPassivePopup.message( "Some title", "This is the main text", px, this );

This screenshot shows a popup with both a caption and a main text which is being displayed next to the toolbar icon of the window that triggered it:

"A passive popup"

For more control over the popup, you can use the setView(QWidget *) method to create a custom popup.

    KPassivePopup *pop = new KPassivePopup( parent );

    KVBox *vb = new KVBox( pop );
    (void) new QLabel( "<b>Isn't this great?</b>", vb);

    KHBox *box = new KHBox( vb );
    (void) new QPushButton( "Yes", box );
    (void) new QPushButton( "No", box );

    pop->setView( vb );
    pop->show();

Signal Documentation

clicked ( )

Emitted when the popup is clicked.

Signal syntax:: QObject.connect(source, SIGNAL("clicked()"), target_slot)

clicked	(	QPoint	pos
	)

Emitted when the popup is clicked.

Signal syntax:: QObject.connect(source, SIGNAL("clicked(const QPoint&)"), target_slot)

Method Documentation

__init__	(	self,
		QWidget	parent=0,
		Qt::WFlags	f=0
	)

Creates a popup for the specified widget.

__init__	(	self,
		int	parent
	)

Creates a popup for the specified window.

QPoint anchor ( self )

Returns the position to which this popup is anchored.

bool autoDelete ( self )

Returns:: true if the widget auto-deletes itself when the timeout occurs.

See also:: setAutoDelete

QPoint calculateNearbyPoint	(	self,
		QRect	target
	)

Calculates the position to place the popup near the specified rectangle.

QRect defaultArea ( self )

If no relative window (eg taskbar button, system tray window) is available, use this rectangle (pass it to moveNear()). Basically KWindowSystem.workArea() with width and height set to 0 so that moveNear uses the upper-left position.

Returns:: The QRect to be passed to moveNear() if no other is available.

hideEvent	(	self,
		QHideEvent	a0
	)

Reimplemented to destroy the object when autoDelete() is enabled.

mouseReleaseEvent	(	self,
		QMouseEvent	e
	)

Reimplemented to detect mouse clicks.

moveNear	(	self,
		QRect	target
	)

Moves the popup to be adjacent to the icon of the specified rectangle.

paintEvent	(	self,
		QPaintEvent	pe
	)

Overwrite to paint the border when PopupStyle == Balloon. Unused if PopupStyle == Boxed

positionSelf ( self )

This method positions the popup.

setAnchor	(	self,
		QPoint	anchor
	)

Sets the anchor of this popup. The popup tries automatically to adjust itself somehow around the point.

setAutoDelete	(	self,
		bool	autoDelete
	)

Enables / disables auto-deletion of this widget when the timeout occurs. The default is false. If you use the class-methods message(), auto-deletion is turned on by default.

setPopupStyle	(	self,
		int	popupstyle
	)

Sets the visual appearance of the popup.

See also:: PopupStyle

setTimeout	(	self,
		int	delay
	)

Sets the delay for the popup is removed automatically. Setting the delay to 0 disables the timeout, if you're doing this, you may want to connect the clicked() signal to the hide() slot. Setting the delay to -1 makes it use the default value.

See also:: timeout

setView	(	self,
		QWidget	child
	)

Creates a standard view then calls setView(QWidget*) .

setView	(	self,
		QString	caption,
		QString	text=QString()
	)

Creates a standard view then calls setView(QWidget*) .

setView	(	self,
		QString	caption,
		QString	text,
		QPixmap	icon
	)

Creates a standard view then calls setView(QWidget*) .

setVisible	(	self,
		bool	visible
	)

show ( self )

Shows the popup in the given point

show	(	self,
		QPoint	p
	)

Shows the popup in the given point

KVBox standardView	(	self,
		QString	caption,
		QString	text,
		QPixmap	icon,
		QWidget	parent=0
	)

Returns a widget that is used as standard view if one of the setView() methods taking the QString arguments is used. You can use the returned widget to customize the passivepopup while keeping the look similar to the "standard" passivepopups.

After customizing the widget, pass it to setView( QWidget* )

Parameters:

	caption	The window caption (title) on the popup
	text	The text for the popup
	icon	The icon to use for the popup
	parent	The parent widget used for the returned KVBox. If left 0L, then "this", i.e. the passive popup object will be used.

Returns:: a KVBox containing the given arguments, looking like the standard passivepopups.

See also:: setView( QWidget * )

See also:: setView( const QString&, const QString& )

See also:: setView( const QString&, const QString&, const QPixmap& )

int timeout ( self )

Returns the delay before the popup is removed automatically.

updateMask ( self )

Updates the transparency mask. Unused if PopupStyle == Boxed

QWidget view ( self )

Returns the main view.
