KFontChooser Class Reference

from PyKDE4.kdeui import *

Inherits: QWidget → QObject

Detailed Description

A font selection widget.

While KFontChooser as an ordinary widget can be embedded in custom dialogs and therefore is very flexible, in most cases it is preferable to use the convenience functions in KFontDialog.

Signal Documentation

fontSelected	(	QFont	font
	)

Emitted whenever the selected font changes.

Signal syntax:: QObject.connect(source, SIGNAL("fontSelected(const QFont&)"), target_slot)

Method Documentation

__init__	(	self,
		QWidget	parent=0,
		KFontChooser.DisplayFlags	flags=KFontChooser.DisplayFrame,
		QStringList	fontList=QStringList(),
		int	visibleListSize=8,
		Qt::CheckState	sizeIsRelativeState=0
	)

Constructs a font picker widget. It normally comes up with all font families present on the system; the getFont method below does allow some more fine-tuning of the selection of fonts that will be displayed in the dialog.

Consider the following code snippet;

    QStringList list;
    KFontChooser.getFontList(list, KFontChooser.SmoothScalableFonts);
    KFontChooser *chooseFont = new KFontChooser(0, NoDisplayFlags, list);

The above creates a font chooser dialog with only SmoothScaleble fonts.

Parameters:

parent The parent widget.

flags

Defines how the font chooser is displayed.

See also:: DisplayFlags

Parameters:

	fontList	A list of fonts to display, in XLFD format. If no list is formatted, the internal KDE font list is used. If that has not been created, X is queried, and all fonts available on the system are displayed.
	visibleListSize	The minimum number of visible entries in the fontlists.
	sizeIsRelativeState	If not zero the widget will show a checkbox where the user may choose whether the font size is to be interpreted as relative size. Initial state of this checkbox will be set according to *sizeIsRelativeState, user choice may be retrieved by calling sizeIsRelative().

__init__	(	self,
		KFontChooser	a0
	)

QColor backgroundColor ( self )

Returns:: The background color currently used in the preview (default: the base color of the active colorgroup)

QColor color ( self )

Returns:: The color currently used in the preview (default: the text color of the active color group)

enableColumn	(	self,
		int	column,
		bool	state
	)

Enables or disable a font column in the chooser.

Use this function if your application does not need or supports all font properties.

Parameters:

	column	Specify the columns. An or'ed combination of FamilyList, StyleList and SizeList is possible.
	state	If false the columns are disabled.

QFont font ( self )

Returns:: The currently selected font in the chooser.

KFontChooser.FontDiffFlags fontDiffFlags ( self )

Returns:: The bitmask corresponding to the attributes the user wishes to change.

QString sampleText ( self )

Returns:: The current text in the sample text input area.

setBackgroundColor	(	self,
		QColor	col
	)

Sets the background color to use in the preview.

setColor	(	self,
		QColor	col
	)

Sets the color to use in the preview.

setFont	(	self,
		QFont	font,
		bool	onlyFixed=0
	)

Sets the currently selected font in the chooser.

Parameters:

	font	The font to select.
	onlyFixed	Readjust the font list to display only fixed width fonts if true, or vice-versa.

setSampleBoxVisible	(	self,
		bool	visible
	)

Shows or hides the sample text box.

Parameters:

visible

Set it to true to show the box, to false to hide it.

setSampleText	(	self,
		QString	text
	)

Sets the sample text.

Normally you should not change this text, but it can be better to do this if the default text is too large for the edit area when using the default font of your application.

Parameters:

text

The new sample text. The current will be removed.

setSizeIsRelative	(	self,
		Qt::CheckState	relative
	)

Sets the state of the checkbox indicating whether the font size is to be interpreted as relative size. NOTE: If parameter sizeIsRelative was not set in the constructor of the widget this setting will be ignored.

QSize sizeHint ( self )

Reimplemented for internal reasons.

Qt::CheckState sizeIsRelative ( self )

Returns:: Whether the font size is to be interpreted as relative size (default: QButton:Off)

Static Method Documentation

getFontList	(	QStringList	list,
		long	fontListCriteria
	)

Creates a list of font strings.

Parameters:

	list	The list is returned here.
	fontListCriteria	should contain all the restrictions for font selection as OR-ed values

See also:: KFontChooser.FontListCriteria for the individual values

Enumeration Documentation

DisplayFlag

FixedFontsOnly only show fixed fonts, excluding proportional fonts

DisplayFrame show a visual frame around the chooser

ShowDifferences display the font differences interfaces

Enumerator:

NoDisplayFlags = 0
FixedFontsOnly = 1
DisplayFrame = 2
ShowDifferences = 4

FontColumn

FamilyList - Identifies the family (leftmost) list.

StyleList - Identifies the style (center) list.

SizeList - Identifies the size (rightmost) list.

Enumerator:

FamilyList = 0x01
StyleList = 0x02
SizeList = 0x04

FontDiff

FontDiffFamily - Identifies a requested change in the font family.

FontDiffStyle - Identifies a requested change in the font style.

FontDiffSize - Identifies a requested change in the font size.

Enumerator:

NoFontDiffFlags = 0
FontDiffFamily = 1
FontDiffStyle = 2
FontDiffSize = 4
AllFontDiffs = FontDiffFamily\|FontDiffStyle\|FontDiffSize

FontListCriteria

The selection criteria for the font families shown in the dialog.

FixedWidthFont when included only fixed-width fonts are returned.

The fonts where the width of every character is equal.

ScalableFont when included only scalable fonts are returned;

certain configurations allow bitmap fonts to remain unscaled and thus these fonts have limited number of sizes.

SmoothScalableFont when included only return smooth scalable fonts.

this will return only non-bitmap fonts which are scalable to any size requested. Setting this option to true will mean the "scalable" flag is irrelavant.

Enumerator:

FixedWidthFonts = 0x01
ScalableFonts = 0x02
SmoothScalableFonts = 0x04
