Title: How To keep GUI hidden with LAYISO COMMAND
Post by: jrupert on February 14, 2014, 07:17:53 AM

I have the following function...note that the GUI is modeless.

(DEFUN c:GBSCC_FormGBSCC_BTNIsolateLayers_OnClicked (/)
(DCL_FORM_HIDE GBSCC_FormGBSCC T)
(alert "Select Layers to Isolate and press {ENTER}")
(COMMAND "layiso")
(DCL_FORM_SHOW GBSCC_FormGBSCC)
)

What is happening is that the user has to either drag the GUI out of the way, or close it, to execute the selection process from COMMAND "layiso".

What I want to happen is that the GUI remains hidden until the COMMAND "layiso" has been completed.

Anyone have any suggestions?

This looks like a case of execution continuing before the command is finished. Try this:

Code (autolisp) Select


(DEFUN c:GBSCC_FormGBSCC_BTNIsolateLayers_OnClicked (/)
    (DCL_FORM_HIDE GBSCC_FormGBSCC T)
    (alert "Select Layers to Isolate and press {ENTER}")
    (COMMAND "layiso")
    (while (not (zerop (getvar "CMDACTIVE"))) (command pause))
    (DCL_FORM_SHOW GBSCC_FormGBSCC)
)

Hello, sorry, I have ignored that your form is modeless, but nevertheless you have to start layiso asynchronounsly. Please switch the control's EventInvoke property to Asynchronous instead of KeepFocus.
