[General] How to delete a button from a dialogue

[sethmachine]

Hi,

I see you can add buttons to a dialogue, but how do you remove them?

Or do I have to remake the dialogue each time I want to remove a button?

You have to clear it with DialogClear() and then re-add the buttons. Lame, huh?

So dialog.DialogClear() removes all of its buttons, but the dialog still exists (i.e. I don't have to destroy it and then remake it)?

If I have an array of those buttons, will they get deleted?

Also, if I destroy a dialogue, but still have an array of its buttons, do those still exist?

All of the buttons in the dialog will get removed. The array if it points to those that were deleted will point to nothing anymore.

When destroying a dialog it destroys all buttons along with it. The array will point to nothing. ( don't forget to null the array to get back the lost handles.)

Null the entire array in both cases, or null each of its entries?

I would null in both cases.

Just to summarize my understanding, I should do this in both cases?

call DialogDestroy(myDialog)
for i range 0 to size of myBttns
  set myBttns[i] = null
endfor
set myBttns = null
...

call DialogClear(myDialog)
for i range 0 to size of myBttns
  set myBttns[i] = null
endfor
set myBttns = null
...
