TD-23383: Problem disabling a form

Post by erasmo » 07 Feb 2017, 11:58

Hello

I have an unusual behavior in TD63sp2up1 when disabling a form in an MDI, this form is sent back from other open forms. In TD61 (I use sp3) and earlier this behavior does not occur, disabled forms maintains their Z orders.

I put samples attached.

Hi Erasmo,

I have quickly hacked a workaround for this issue.
You are able to prevent (as one of the options) that a window changes it's Z-order.

The workaround here is that when a form is getting disabled, the Z-order change will be ignored and will keep the original position.
Have a look at frm2 implementation.

frm3 sends a msg to frm2 instructing to disable itself. On frm2 the Z-order change will be prevented until it is back enabled again when frm3 closes.
