Hi all,
I have a problem using dialog-boxes in Personal Pascal. I want to
define a dialog box without an 'exit button'. However when I put this box
on the screen by the statement:
Pushed := Do_Dialog(The_Box, The_First_Button);
then the machine hangs in the Do_Dialog procedure. It is not possible to
return from Do_Dialog because I defined no there is no 'exit button'.
My question: Is there a work-around for this problem (without using windows)
to display a dialog box and get rid of it without user intervention. A possible
purpose I think of using this, is when the system is reading a file and the
user has to wait. In this case it should be possible to display the message:
Wait, reading from inputfile...
in a dialog box. When the machine is ready reading the file, the dialog box
can be removed. But, as I already mentioned, there is no way out without
clicking the mouse on an 'exit button'.

Yes this is possible to do, what you want, but you don't want to call
do_dialog. There is I think a routine to simply draw the dialog object,
I use it in a program I had written using PP. Will look it up tonight,
as I recall, it was not documented. Essentially it is the GEM function
objc_draw(), that this routine calls.

In version 2 of PP, there is a procedure show_dialog(), it takes
2 parameters the first is the dialog ptr of the dialog you wish to display
and the second, is the tree index to start drawing down (to draw whole dialog
, this value should be 0).
ex: show_dialog(my_dialog,0);
In version 1 of PP, this routine doesn't exist, so you have to do this
declare the external procedure obj_draw like this.
procedure obj_draw(box:dialog_ptr; { dialog to display }
item:tree_index; { index of where to start drawing down }
depth:integer; { how deep to go }
x:integer; { location of dialog (x,y (upper left corner }
y:integer;
w:integer; { width & height }
h:integer); external;
Then just call this routine like you would call the C function
objc_draw, as they are the same. This procedure was undocumented in PP
version 1.
