I have been experimenting with programming using GEM calls and I
ran into a problem I cannot resolve. I tried to set up a dialog
box as follows:
--------------------------------------
<-- Obj_Type=G_BOX
Obj_Flag=NONE
Obj_State=NORMAL
----------------
Click Here <-- Obj_Type=G_BOXTEXT
-------------------------------------- Obj_Flag=EXIT
Obj_State=NORMAL
The G_BOX object is the ROOT where:
Obj_Next=-1 Obj_Head=1 Obj_Tail=1
The G_BOXTEXT is the child where:
Obj_Next=0 Obj_Head=-1 Obj_Tail=-1
I want to display messages within the dialog box and have the user
skip to the next message by clicking on the G_BOXTEXT object. The
problem I am having is that I cannot figure out the parent-child-
sibling relationship of the G_TEXT objects that I will have to
place within the G_BOX object. Would the new G_TEXT objects be
children of G_BOX? What values for Obj_Next, Obj_Head and
Obj_Tail would I use for these additional objects? HELP, I am
stuck!rjung@nunki.usc.edu (Robert allen Jung) (02/27/89)

First piece of advice: Use a resource construction program (RCP). Building GEM resources by hand is a mind-numbing experience that's no fun for the average human being. Now, if you were to have many G_TEXT objects (strings for your messages) in your root box, they would be children of the root (since they are _inside_ the box). The G_BOXTEXT button would be another sibling to them. Basically, your object tree would look something like: Root box (G_BOX) ____________/ \_______________ | | v v First G_TEXT <--> Next G_TEXT <--:--> G_BOXTEXT string string button The numeric order doesn't really make a difference. --R.J. B-) P.S. I'm not a guru with the inner mechanics of GEM dialogs; I prefer to stay in the stratosphere of the RCP. However, I'm pretty sure of what I have up there. ============================================================================= Disclaimer: This message was written with my authorization # ## # # ## # Mailing address: rjung@nunki.usc.edu ## ## ## (It's easier to just use the reply function, tho) #### ## ####
