onMouseEnter EH

[gc8 981]

Hi 

 I was trying to get the MouseEnter EH to work on control but it doesn't trigger. mousemoving EH works though.

Here's my code:

 

_id = _soldiersList ctrlAddEventHandler ["MouseEnter",
{
 params ["_ctrl"];
 
 systemchat "HOVER";
}];
_id = _soldiersList ctrlAddEventHandler ["MouseExit",
{
 params ["_ctrl"];

 systemchat "HOVER out";
}];

 

Anyone know whats wrong?

 

thx!

STATIC: No
BUTTON: Yes
SLIDER: Yes (Enter delayed, Exit only when focused)
COMBO: No
LISTBOX: No
TOOLBOX: Yes
CHECKBOXES: Yes
PROGRESS: No
HTML: No
ACTIVETEXT: Yes (on the letters)
TREE: Yes
STRUCTURED_TEXT: Yes
CONTROLS_GROUP: No
SHORTCUTBUTTON: Yes
XLISTBOX: Yes
XSLIDER: Yes/No (delayed, exit only when dragging)
MAP_MAIN: No

 

Just tested the EHs on some control types and these are the results. Seems kind of random to me. In the cases of the SLIDER and XSLIDER the EH were really wonky.

@7erra Thanks, that's good to know! I was also thinking it might only work on buttons and such... so I take STATIC means backgrounds too. Not very useful EH then lol

Apparently you can use a STRUCTURED_TEXT control as background and assign the EH to this control though

I don't know about that, it's a bit too hacky solution for me. So I'll think about workaround or something... 

thx though!

MouseMoving EH combined with getMousePosition and inArea commands.

Spoiler

_null = [] spawn {
	disableSerialization;
	createDialog "RscDisplayCommon";
	waitUntil{ !isNil{ uiNamespace getVariable "RscDisplayCommon" } };
	_display = uiNamespace getVariable "RscDisplayCommon";

	_ctrl = _display ctrlCreate[ "ctrlListbox", 10001 ];
	_ctrl ctrlSetPosition[ 0, 0, 1, 1 ];
	_ctrl ctrlCommit 0;

	_txt = _display ctrlCreate[ "ctrlStatic", 10002 ];
	_txt ctrlSetPosition[ 0.4, 0.48, 0.2, 0.02 ];
	_txt ctrlCommit 0;

	_display displayAddEventHandler[ "MouseMoving", {
		params[ "_display" ];

		_ctrl = _display displayCtrl 10001;
		ctrlPosition _ctrl params[ "_x", "_y", "_w", "_h" ];
		_w = _w / 2;
		_h = _h / 2;
		_isMouseOver = getMousePosition inArea[ [ _x + _w, _y + _h ], _w, _h, 0, true ];

		_wasMouseOver = _display getVariable[ "TAG_mouseEntered", false ];

		_txt = _display displayCtrl 10002;
		if ( !_wasMouseOver && _isMouseOver ) then {
			_txt ctrlSetText "Entered";
		};
		if ( _wasMouseOver && !_isMouseOver ) then {
			_txt ctrlSetText "Exited";
		};

		_display setVariable[ "TAG_mouseEntered", _isMouseOver ];
	}];
};

@Larrow thanks! That is a nice solution, using it in my project (works good!).
