如何实现交互对话框(选择一个点)

zdfwyh

我想建立一个对话框,上面有一个按钮,点击后隐藏对话框,从CAD中选取一点,然后显示对话框,和坐标.不知如何实现这个交互过程?请高手指点迷津.

void AsdkAcUiDialogSample::OnButtonPoint()
{
    // Hide the dialog and give control to the editor
    BeginEditorCommand();

    ads_point pt;

    // Get a point
    if (acedGetPoint(NULL, "\nPick a point: ", pt) == RTNORM) {
        // If the point is good, continue
        CompleteEditorCommand();
        m_strXPt.Format("%g", pt[X]);
        m_strYPt.Format("%g", pt[Y]);
        m_strZPt.Format("%g", pt[Z]);
        DisplayPoint();
    } else {
        // otherwise cancel the command (including the dialog)
        CancelEditorCommand();
    }

}
