How to cancel a jig drag loop from a modeless dialog

hbxiaogui — Mon, 08 May 2023 02:59:17 GMT

I have a modeless dialog showing during jig.

There is a command in modeless dialog that uses acedEntSel() to pick an entity, and it returns RTREJ immediately.

I think the reason is I'm inside the jig. drag() loop, so I can't use acedEntSel().

So how can I cancel the drag loop from a modeless dialog?

I can't find a way to cancel the drag loop,and finally I move the command from dialog into my jig class, then use keywords to pick the entity.

Try to send <ESC> like this:

AcApDocument *pCurrDoc = acDocManager->curDocument(); LPCTSTR cmd = _T("\x1B"); // ESC Acad::ErrorStatus es = acDocManager->sendStringToExecute(pCurrDoc, cmd);

If you have added a keyword to cancel the jig, you can also send the keyword with cmd=_T("yourkey\n").

I want to change the jig entity's property by picking another entity, the jig loop should still be there after the pick action.

I tried the solution by sending esc, it seems the esc will execute later than the pick action.

I don't think that it is possible to call acedEntSel() during a jig loop. If you need to select an entity "within" the jig, you should exit the drag loop, select and re-enter the jig by calling jig.drag().

The effect of

acDocManager->sendStringToExecute(pCurrDoc, cmd);

is the same as entering cmd on the commandline. cmd is sent to AutoCAD's command queue and will be processed as soon as the command processor is ready to parse input.

Thanks!

I add the button back to my dialog, and the click event only sends a keyword.

Now the loop works as expected.
