How to close addon panel with ESC key?

[cristimirt]

Sorry for writing in English, but I don't know Russian.
Also, I'm sorry if this question was asked and answered already, but it's hard for me to search the forum without know Russian.

I'm trying to close the panel of my addon by using the ESC key. I know of two ways to bind this key to a function, but each has a drawback.

• One is to use 'ReactionEsc' in a WidgetEditLine (like it's done in BuildManager). This works but it requires to have a WidgetEditLine in focus, which I don't like, because I can't use it to cancel actions (PicCastbar has this problem)
• The other one is to use 'bindSections' in a WidgetForm. I can bind the 'esc_pressed' action to a function using common.RegisterReactionHandler. This works without the need to have specialized widgets, but it introduces an annoyance : it also opens the Escape Menu

By looking a the lua code of the 1.0 addons, I can see that they use a kind of manager that keeps track of what widgets are visible and their order, so when you press the ESC key, the correct one closes, and the Menu only shows if there are no other widgets to hide. But of course, user addons don't have access to this, so we can't add our own widgets to this list.

I've found a quick hack that allows me to close my panel without triggering the Escape Menu, bit I don't like using it. The idea is to disable the EscMenu addon when I open my addon panel, and then enable it again right after I close my panel. This works ok for when you know your panel is not visible for too long and you're careful to always enable it back, but it might cause unforseen problems.

So my question is : Is there a proper way to close addon panels by pressing the escape key, without opening the Escape Menu?
 

PS: You can reply in russian, I will use Google Translate. Thank you!

 This addon allows to close it with esc, maybe it will help.

Yeah, BuildManager. I looked at it, and it's where I found out about using WidgetEditLine. But this method works only when you have at least an input field in your window

A "hack" that you can try is to put your addon as a child of EscMenu

stateMainForm:EscMenu:AddChild(mainForm)

i don't know if it will work, but i expect this to work like the other panels in the EscMenu (like video settings, etc.)
