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.
| enum FontColumn { FamilyList=0x01, StyleList=0x02, SizeList=0x04} | FontColumn |
FamilyList - Identifies the family (leftmost) list.
StyleList - Identifies the style (center) list.
SizeList - Identifies the size (rightmost) list.
| enum FontDiff { FontDiffFamily=0x01, FontDiffStyle=0x02, FontDiffSize=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.
| KFontChooser (QWidget *parent = 0L, const char *name = 0L,
bool onlyFixed = false,
const QStringList &fontList = QStringList(),
bool makeFrame = true, int visibleListSize=8,
bool diff = false, QButton::ToggleState *sizeIsRelativeState = 0L )
| KFontChooser |
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,SmoothScalableFonts); KFontChooser chooseFont = new KFontChooser(0, "FontList", false, list);
The above creates a font chooser dialog with only SmoothScaleble fonts.
Parameters:
| parent | The parent widget. |
| name | The widget name. |
| onlyFixedFonts | 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 KFontDialog::getFontDiff(). |
| 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(). |
| ~KFontChooser ()
| ~KFontChooser |
[virtual]
Destructs the font chooser.
| void enableColumn ( int column, bool state )
| enableColumn |
Enables or disable a font column in the chooser.
Use this function if your application does not need or supports all font properties.
Parameters:
| font | Specifie the columns. An or'ed combination of
FamilyList, StyleList and SizeList is possible.
|
| state | If false the columns are disabled.
|
| void setFont ( const QFont &font, bool onlyFixed = false )
| setFont |
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.
|
| int fontDiffFlags ()
| fontDiffFlags |
Returns: The bitmask corresponding to the attributes the user wishes to change.
| QFont font ()
| font |
[const]
Returns: The currently selected font in the chooser.
| void setColor ( const QColor & col )
| setColor |
Sets the color to use in the preview.
| QColor color ()
| color |
[const]
Returns: The color currently used in the preview (default: black)
| void setBackgroundColor ( const QColor & col )
| setBackgroundColor |
Sets the background color to use in the preview.
| QColor backgroundColor ()
| backgroundColor |
[const]
Returns: The background color currently used in the preview (default: white)
| void setSizeIsRelative ( QButton::ToggleState relative )
| setSizeIsRelative |
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.
| QButton::ToggleState sizeIsRelative ()
| sizeIsRelative |
[const]
Returns: Whether the font size is to be interpreted as relative size (default: QButton:Off)
| QString sampleText ()
| sampleText |
[const]
Returns: The current text in the sample text input area.
| void setSampleText ( const QString &text )
| setSampleText |
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. |
| QString getXLFD ( const QFont &theFont )
| getXLFD |
[static]
Converts a QFont into the corresponding X Logical Font Description (XLFD).
Parameters:
| theFont | The font to convert. |
Returns: A string representing the given font in XLFD format.
| enum FontListCriteria { FixedWidthFonts=0x01, ScalableFonts=0x02, SmoothScalableFonts=0x04 } | 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.
| void getFontList ( QStringList &list, uint fontListCriteria)
| getFontList |
[static]
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: FontListCriteria, for, the, individual, values
| QSize sizeHint ( void )
| sizeHint |
[const virtual]
Reimplemented for internal reasons.
| void fontSelected ( const QFont &font )
| fontSelected |
[signal]
Emitted whenever the selected font changes.
| void virtual_hook ( int id, void* data )
| virtual_hook |
[protected virtual]
