DrawThemeChasingArrows

Draws an asynchronous arrows indicator.



 
pascal OSStatus DrawThemeChasingArrows (

                     const Rect *bounds,

                     UInt32 index,

                     ThemeDrawState state,

                     ThemeEraseUPP eraseProc,

                     UInt32 eraseData);

bounds: A pointer to a structure of type Rect . Before calling DrawThemeChasingArrows , set the rectangle to contain the asynchronous arrows, in local coordinates.
index: An unsigned 32-bit value. Pass a value specifying the current animation step of the arrows. To animate the arrows, increment the initial value by 1 with each call to DrawThemeChasingArrows .
state: A value of type ThemeDrawState . Pass a constant specifying the state in which to draw the asynchronous arrows indicator; see Theme Draw State Constants . The asynchronous arrows indicator can be drawn as active or inactive; passing kThemeStatePressed produces an error.
eraseProc: A value of type ThemeEraseUPP . If you have a custom background, pass a universal procedure pointer to an application-defined function such as that described in MyThemeEraseProc . DrawThemeChasingArrows calls that function to erase the background before drawing the asynchronous arrows. If you pass NULL , no erasing occurs.
eraseData: An unsigned 32-bit integer. Provide any data to be passed in to the eraseData parameter of the callback function specified in the eraseProc parameter.
function result: A result code; see Result Codes .

DISCUSSION

The DrawThemeChasingArrows function draws a theme-compliant asynchronous arrows (also known as "chasing arrows") indicator.
