Okay Im making a Cocoa app and there are two Interface elements I would like to use, but I can't find em anywhere. The View triangle that lets you show hide elements in a window as well as the chasing arrows for indeterminate proccesing. Both of these appear in AppearanceSampler but i really want these widgets. Why wont Ineterface BUilder give them to me.
Appearance Sample seems to be a Carbon application (the Project Builder file can be found at '/Developer/Examples/Carbon/AppearanceSample/AppearanceSample.pbxproj'). Looking through Interface Builder the only place the chasing arrows appear is in the 'Carbon/Other' section.
Both of the UI elements you mention are Carbon-only. For chasing arrows, I suggest using the OAChasingArrowsProgressIndicator class in the OmniAppKit. The nice thing about it is that it isn't dependant on the rest of the framework, so you only need to grab the individual source files for the class. For the disclosure triangle, just grab some images of the triangle and use them in an NSButton as Image and Alternate Image. Simple .
If you're talking about the disclosure button found in Save dialogs, that's available in Cocoa, but for some reason it's not public API. The class name is NSDisclosureButton, I think. Find out more with class-dump.
