Member Function Documentation

uiFontButtonFont()

void uiFontButtonFont	(	uiFontButton *	b,
		uiFontDescriptor *	desc )

Returns the selected font.

Parameters

	b	uiFontButton instance.
[out]	desc	Font descriptor. [Default: OS-dependent].

Note

Make sure to call uiFreeFontButtonFont() to free all allocated resources within desc.

uiFontButtonOnChanged()

void uiFontButtonOnChanged	(	uiFontButton *	b,
		void(*	f )(uiFontButton *sender, void *senderData),
		void *	data )

Registers a callback for when the font is changed.

Parameters

b	uiFontButton instance.
f	Callback function. sender Back reference to the instance that triggered the callback. senderData User data registered with the sender instance.
data	User data to be passed to the callback.

Note

Only one callback can be registered at a time.

uiFreeFontButtonFont()

void uiFreeFontButtonFont

(

uiFontDescriptor *

desc

)

Frees a uiFontDescriptor previously filled by uiFontButtonFont().

After calling this function the contents of desc should be assumed undefined, however you can safely reuse desc.

Calling this function on a uiFontDescriptor not previously filled by uiFontButtonFont() results in undefined behavior.

Parameters

desc	Font descriptor to free.

uiNewFontButton()

uiFontButton * uiNewFontButton ( void )

static

Creates a new font button.

The default font is determined by the OS defaults.

Returns

A new uiFontButton instance.
