ToolBar enabling and disabling question [message #21451]

Hello all

Just a simple question.

I want to enable or disable an option in a ToolBar depending in this case if a text has been changed or not.

index.php?t=getfile&id=1731&private=0

For a MenuBar it is easy to do it, but for a ToolBar I do not know the way.

I have tried to do it by a Timer function that calls every 3 seconds to UpdateLayout() and other functions, bot no success.

How can I force a ToolBar to update its layout?.

Best regards
Koldo

It is same as MenuBar

Locking to uppsrc is two method:
1. if you set a control, set enable or disable this control
2. if is calback with text or/and image

you need use this method

Bar::Item&  Bar::Add(bool enable, const UPP::Image& image, Callback cb)

and example you can find in uppsrc/ide/idebar.cpp at line 379 like this:

void Ide::BuildMenu(Bar& menu) {
..........
	b = b && idestate == EDITING; // set enable or disable
=>HERE	menu.Add(b, AK_CLEAN, THISBACK(Clean))
		.Help("Remove all intermediate files");
.............
}

and every time when you want to refresh bar you need call like this:

YOUR_TOOLBAR_CTRL_OBJECT.Set(THISBACK(YOR_CONSTRUCTOR_BAR_FUNCTION));

Other method, maybe what you need... you need to save your references of item Bar::Item& when you add items, when you want to enable or disable you need to call method Enable(IS_NEABLE)

You need to set it again.

See examples/UWord, UWord::SetBar and calls to it.

This perhaps might be automated, which was sort of idea at some time in the past, but in the end I have found that calling 'SetBar' after each change is quite trivial...
