Accessing GUI of CAD through Tcl/Tk
in [TCL]

From: APN on 12 Dec 2009 12:20 Here is short sample to start notepad and open the file dialog (myappdir) 67 % set pid [exec notepad.exe &] 1212 (myappdir) 68 % ::twapi::find_windows -pids [list $pid] -text "Untitled - Notepad" -toplevel true 0x140524 (myappdir) 69 % twapi::set_focus 0x140524 ; twapi::send_keys {%FOabc.txt{ENTER}} 22 (basically sending Alt-F O accelerator followed by name of file and ENTER. See documentation of send_keys for key syntax (follows Visual Basic syntax for keystrokes). If you can do the whole thing with keyboard accelerators, you might try something similar. For an example of painting with a mouse see http://wiki.tcl.tk/20231 However, as others have said, DO NOT USE THIS METHOD. Unless the sequence really short and simple, , this way lies madness. You might try Auto-It for something like this. I have not used it extensively but I think it does more under the covers to block other input, verify the correct windows have focus etc. With TWAPI, you have to do that work yourself using lower level commands. /Ashok On Dec 12, 9:30 pm, "S-Y.

IMHO they are all good and point basicly the same way. To resume on the issue "Read the menu of a foreign application and click on an item": - nobody how replied knows, how to read the captions of menu items of a foreign application. So this way and request stays unanswered. - I supposed, there might be a tool to read from screen output (OCR- Recognition). At least, this is possible to program but very difficult. I don't know of such a program existing. Regards, Harald

I guess I might have used the wrong language. I am still hoping to use TWAPI, because that will save me a lot of time. I should say that I already know the "Caption" on the child windows, belonging to the parent window. So, maybe it is possible (I am not sure) to 1. find the "handle" of that item with the specific caption, under the specific parent window 2. send key strokes, or mouse click to that "handle" From the previous examples, I can see that we can send key strokes to a window with specific handle. Is it not possible to loop through all the available child windows, get the caption, until the specific one is found ? Regards S-Y. Chen |
