void uiFontButtonFont | ( | uiFontButton * | b, |
uiFontDescriptor * | desc | ||
) |
Returns the selected font.
b | uiFontButton instance. | |
[out] | desc | Font descriptor. [Default: OS-dependent]. |
uiFreeFontButtonFont()
to free all allocated resources within desc
. void uiFontButtonOnChanged | ( | uiFontButton * | b, |
void(*)(uiFontButton *sender, void *senderData) | f, | ||
void * | data | ||
) |
Registers a callback for when the font is changed.
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. |
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.
desc | Font descriptor to free. |
uiFontButton * uiNewFontButton | ( | void | ) |
Creates a new font button.
The default font is determined by the OS defaults.
