Dynamic Ctrl frame [message #53746]

I would like a coloured frame to appear around a control when the mouse passes over it, like the image:
index.php?t=getfile&id=6059&private=0

I have tried it in two ways:
- Playing with CtrlFrame. Unfortunately the colors are set as const, so they cannot be changed using MouseEnter()
- Working with another frame control. Unfortunately I do not know how a child control can adapt to parent, but staying around it, not inside it (as with SizePos()). I would prefer that this child frame control would be created automatically in the parent field construction.

Thank you.

Hello Koldo,
I've been playing around with Chameleon lately and
I think you need to look at the EditField::Style.edge[]

struct Style : ChStyle<Style> {
		Color paper;
		Color disabled;
		Color focus;
		Color invalid;
		Color text, textdisabled;
		Color selected, selectedtext;
		Color selected0, selectedtext0; // If does not have focus...
		[b]Value edge[4];[/b] // border (for various active edge states)
		Value coloredge; // border mask for adding color, e.g. round borders with red Error
		bool  activeedge;
		int   vfm;
	};

and using:

enum {
	CTRL_NORMAL, CTRL_HOT, CTRL_PRESSED, CTRL_DISABLED,
	CTRL_CHECKED, CTRL_HOTCHECKED
};

So if you set edge[CTRL_HOT] to the right style image, you will probably get what you want

If you want to apply it to all EditField children, add at application init:

EditField::StyleDefault.Write().edge[CTRL_HOT] = YoureStyle;

Note: this will only work for all EditField children ... not all Ctrls

If you want to apply it to a specfic Ctrl (not all), this should do the trick :
Quote:

static EditField::Style myCtrlStyle = EditField::StyleDefault();
myCtrlStyle.edge[CTRL_HOT] = YoureStyle;
...
myCtrl.SetStyle(myCtrlStyle);

You may need to replace 'EditField::Style' by '<EditFieldChildType>::Style' (depending on you're EditXxxx Ctrl)

Thank you Didier

The idea was to apply it to a set of Ctrl, and that when the mouse is out of the Ctrl, it would remain selected until other Ctrl of the set is chosen.

It would be like a Switch (from a set of Ctrl, you choose just one), but with a visual signal around any Ctrl of the set, and that is activated just by hovering on the Ctrl instead of by clicking it.
