How to create an graphic editable window?

Hi,

 I would like to create a graphic window with a dockable form by programming like below:

win1 = hiCreateWindow('default "graphics" "zl_win" "" t)

ses1 = hiCreateWindow('default "session" "zl_ses" "" t)

dock1 = hiCreateDockWindow(?appType "zl_dock1" ?widgetType "form" ?form hiCreateAppForm(?name 'TheForm1 ?formTitle "Test" ?fields list(list(layer_id 20:0 220:30 160))))

hiDockWindow(?window dock1 ?session ses1)

hiDisplayWindow(win1 ses1)

After the window is created, I would like to draw layout within it, however, it says that:

*WARNING* No application registered for prefix zl_win

Then I write: hiRegisterBindKeyPrefix("zl_win" "graphics"). After that, I tried to use the command:

dbCreateRect(geGetEditRep(window(10)) list((0 0) (10 10)) list("met1" "drawing"))

to draw a rect. It failed and said that:

*WARNING* (GE-2067): geGetEditCellView: There is no graphical edit environment assigned to window(10) because the window is not a graphic editor window.

Make sure that your current window is a valid graphic editor window.

If it is a valid graph editor window, contact customer service to investigate this issue.

I don't know how to assign a graphical edit environment to the window, besides I think I already created a graphic window. Why isn't it recongnized?


Thanks in advance
