dialog - OPENDCL(AUTOCAD): avoid exiting modeless dialog if [ENTER] is pressed

Question

我正在寻找一种方法，以避免在按下 [ENTER] 时退出 autocad(由 opendcl 创建)中的无模式对话框。

有什么想法吗？

谢谢， 丹尼斯

我已经为 OpenDCL 网格系统实现了这样的功能。您必须激活表单上的 OnCancelClose 函数。我就是这样做的:

(defun c:MyFunction_Form1_OnCancelClose (Reason /)
    ;; Reason = 0 when Enter is pressed
    (if (= Reason 0)
        (progn
            ;; Shift active editing cell one row down
            (setq rowAndCol(dcl_Grid_GetCurCell MyFunction_Form1_revisions))
            (dcl_Grid_StartCellEdit MyFunction_Form1_revisions (1+ (car rowAndCol)) (cadr rowAndCol))
        )
    )

    ;; Reason = 1 when ESC key is pressed, or the closing button in the titlebar
    ;; is clicked. Hence, enter won't work to cancel the dialog
    (/= Reason 1)
)
