CHAPTER 5

Software

90 Control Strip Module Reference

svAllSmallData 0x0000FF00 load small 16-by-16-pixel icons ('ics#',

'ics4', 'ics8')

svAllMiniData 0x00FF0000 load mini 12-by-12-pixel icons ('icm#',

'icm4', 'icm8')

These values may be OR-ed together to load combinations of icon sizes.

SBGetDetachIconSuite returns an appropriate error code if it’s unsuccessful,

or 0 if if was able to load the icon suite. Note that if none of the icons comprising

the icon suite could be found, the call returns the error resNotFound.

IMPORTANT

You should call SBGetDetachIconSuite only when the module’s

resource ﬁle is open, which is typically the case during a module’s

initialization call. ▲

SBTrackpopupMenu 5

You can use the SBTrackpopupMenu routine to manage a pop-up menu.

pascal short SBTrackpopupMenu(const Rect *moduleRect,

MenuHandle theMenu);

The SBTrackpopupMenu routine handles setting up and displaying a pop-up menu

associated with a module. The module should pass a pointer to its display rectangle and

a handle to the menu to use. The menu will be displayed just above the module’s

display rectangle, allowing the user to view the current conﬁguration or to change the

settings. SBTrackpopupMenu returns which menu item was selected, or 0 if no item

was selected because the user moved the cursor outside the menu’s bounds.

IMPORTANT

Menus are displayed in the control strip’s font, so don’t use the

CheckItem() routine to mark menu items, because a checkmark is

supported only in the system font. Use the SetItemMark() routine

instead and pass it a bullet (•). ▲

SBTrackSlider 5

You can use the SBTrackSlider routine to display and set an arbitrary parameter.

pascal short SBTrackSlider(const Rect *moduleRect,

short ticksOnSlider,

short initialValue);
