Member Function Documentation

◆ uiFontButtonFont()

void uiFontButtonFont ( uiFontButton * b,
uiFontDescriptor * desc )

Returns the selected font.

Parameters
buiFontButton instance.
[out]descFont descriptor. [Default: OS-dependent].
Note
Make sure to call uiFreeFontButtonFont() to free all allocated resources within desc.

◆ uiFontButtonOnChanged()

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

Registers a callback for when the font is changed.

Parameters
buiFontButton instance.
fCallback function.
sender Back reference to the instance that triggered the callback.
senderData User data registered with the sender instance.
dataUser 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
descFont 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.
