Detailed Description

A font selection widget.

While TDEFontChooser 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 TDEFontDialog.

Member Enumeration Documentation

FontColumn

enum TDEFontChooser::FontColumn

• FamilyList - Identifies the family (leftmost) list.
• StyleList - Identifies the style (center) list.
• SizeList - Identifies the size (rightmost) list.

Definition at line 65 of file tdefontdialog.h.

FontDiff

enum TDEFontChooser::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.

Definition at line 72 of file tdefontdialog.h.

FontListCriteria

enum TDEFontChooser::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.

Constructor & Destructor Documentation

TDEFontChooser()

TDEFontChooser::TDEFontChooser	(	TQWidget *	parent = 0L,
		const char *	name = 0L,
		bool	onlyFixed = false,
		const TQStringList &	fontList = TQStringList(),
		bool	makeFrame = true,
		int	visibleListSize = 8,
		bool	diff = false,
		TQButton::ToggleState *	sizeIsRelativeState = 0L
	)

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;

TQStringList list;
TDEFontChooser::getFontList(list,SmoothScalableFonts);
TDEFontChooser chooseFont = new TDEFontChooser(0, "FontList", false, list);

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

Parameters

parent	The parent widget.
name	The widget name.
onlyFixed	Only display fonts which have fixed-width character sizes.
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.
diff	Display the difference version dialog. See TDEFontDialog::getFontDiff().
makeFrame	Draws a frame with titles around the contents.
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().
