I was wondering about an item that is declared "editText" in a resources template. Is it just like a "TEHandle"? Can you Call: GetDItem(dialog, itemno, &type, &tehandle, &rect); TEIdle(tehandle); (or any Textedit routine) I want to use a textEdit and a scroll bar in a dialog window, I tried to declare a textedit item for the window, and a user Item for the scroll bar, but the "tehandle" that I declared and stored in the item list does'nt act like I expect it to. I want to be able to access some of the "TEHandle" to calculate the postion of the scroll bar at any given time. Can you do this: GetDItem(dialog, itemno, &type, &tehandle, &rect); tehandle = TENew(&rect, &rect); and then use this handle??? Or am I way off track. Any help would be appreciated.

Ideally you would only access this handle by passing it to GetIText and SetIText. A dialog has one TERecord that is shared by all editText items (i.e. it contains the correct values for the currently active editText item. This is all fairly well explained in Chapter 13 The Dialog Manager of Inside Mac Vol I (esp. pg I-408). Hope this helps. -- --scott douglass, Apple Computer CSNet: scott@Apple.CSNet UUCP: {nsc, sun, voder, well, dual}!apple!scott AppleLink: Douglass1 Any opinions above are mine and not necessarily those of Apple Computer.

No, it is a handle to an "editText item", which, in fact, contains the handle to the text (I believe in the first 4 bytes, but I may be wrong on this). >Can you Call: >GetDItem(dialog, itemno, &type, &tehandle, &rect); >TEIdle(tehandle); (or any Textedit routine) No, for the reason stated above. However, if the TEHandle to the CURRENTly active text is in the textH field of the DialogRecord (i.e. in dialog^.textH You can select a specific text item with SelIText(dialog, itemNo, start, end); See IM-I-408,422 Marc Kaufman (kaufman@polya.stanford.edu)
