I always wonder about the need of lines like, Gui, Submit, NoHide and GuiControlGet, out,, AssociatedVar when I retrieve values from Gui controls. Would it be possible to add an option like AutoSubmit so that the associated value automatically gets updated and we don't need the commands to retrieve it?

Something like this,

Performance would take quite the hit :/

That's why it's an option.

Every time you acessed any var's contents, AHK would have to check if it was one associated with a control. Similar to not using #NoEnv, it would still slow down all scripts.

Same as gLabel.

no... gLabel has nothing to do with every variable in a script

gLabel AFAIK works like OnMessage

Then it won't be a problem if it is implemented like OnMessage.

it can't be there are no messages sent when specific variables are accessed every variable would have to be checked each time

Wrong. The variable only needs to be accessed when the control is accessed.

I see. This can be implemented with a g-label, in that case. It is exactly the same as your request except for 2 things:

1. The AutoSubmit option has a 'g' in front of it
2. It requires 3 whole lines (oh noes) added to the script

You could even put that label in a separate file and #Include it at the bottom of your script.

That way the user cannot use gLabel normally. That's why the suggestion would be useful.

The user can simply call GuiControlGet from their g-label to update the variable. An AutoSubmit option seems like it might be convenient, but it probably does not have sufficient net benefit.

I like the idea. Some gui-controls like DateTime, MonthCal, Slider, Tab2, UpDown, already process a built-in "AutoSubmit" when launching the g-label, so why shouldn't the others have it as an option?

Here's as close as you will come to the suggested functionality:
Specify gAutoSubmit for the control's variable to update automatically. If a label with the same name as the control's variable is present, it will be launched immediately after the control's variable is updated. Of course, you could change the last few lines to add a naming convention such as variableName_Label: as opposed to variableName:

This has the same effect as calling GuiControlGet %A_GuiControl% in each of the gLabels; however it will save some lines of code if you have many 'AutoSubmit' controls.
