any improvised ways to double click a grid, i can get my menu by hotspot like i do with normal listbox.......but how to double click ??

Any Ideas ??

If you're only doing something on double-click, I suppose you could stack two hotspots. The first click disables the top one.
The second hotspot will act on the next click, then enable the top one again.

I guess the timer could be used to reset everything in the event the second click never happened...?

It's a little 'rough' but it may give you an idea.

If you're doing something on the single click also, this probably won't work for you...

Here's my work-around. I like it because it doesn't tie up the timer, and its been very stable for my needs.

yup, thats perfect, thanks worm, seems reliable and easy to add

@holtgrewe, you was thinking along the same lines i was, it was a little messy and not always reliable,

also, when you select a cell, you get that tool tip, can that be disabled, i did look at the functions, but theres sooooo many to get to know

@worm - That one's going in the ol' tool box. I'm sure I'll be using that somewhere down the road.:yes

lol, exactly what i tought, stright in the scriplets folder (most of which contain functions written by worm, lol)

I was just thinking about how to do this today. I had a customer moaning about not being able to double-click a row to open a record instead of selecting a row and clicking a button. This is perfect, thanks.

Of course this event should still be added to the grid object.

Nice Worm. I mirrored this project on amsuser.com, here:

yeah i agree, i would have tought a double click event was starndard in this sort of object, but still, the work-a-round works fine with "Grid.SetToolTipsEnabled(false)", else it all looks kinda funky and causes a delay coz the tooltip gets in the way of the 2nd click, or maybe i could disable the tooltip while the mouse is down....that sounds better


also, the "IsInRect" function is one iv often used as supporting other functions but never really took much notice of it till now, very handy and could save a lot of timer code :yes

I just implemented this in one of my apps and it works awesome. Actually it is the Datagrid because it is too much work right now to switch to the Grid, but it works just the same.

I agree, a double-click event should be standard for this kind of object.

Here's my edit of the approach:

GridX = {}
GridX.Border = 2
GridX.HeaderHeight = 21
GridX.DoubleClickSpeed = 280
GridX.CurLastTime = 0
function GridX.IsInRect(m_nX, m_nY, m_tblPos, m_tblSize)
	if (m_nX >= m_tblPos.X + GridX.Border) and 
		(m_nX <= m_tblPos.X + m_tblSize.Width - GridX.Border) and
		(m_nY >= m_tblPos.Y + GridX.HeaderHeight + GridX.Border) and 
		(m_nY <= m_tblPos.Y + m_tblSize.Height - GridX.Border) then
		return true
	else	
		return false
	end
end

if GridX.IsInRect(e_X, e_Y, Grid.GetPos("Grid1"), Grid.GetSize("Grid1")) then
	if e_Type == LEFT_BUTTON_UP then
		local nCurTime =  DLL.CallFunction(_SystemFolder .. "\\winmm.dll", "timeGetTime", "", DLL_RETURN_TYPE_LONG, DLL_CALL_STDCALL)
		if nCurTime - GridX.CurLastTime <= GridX.DoubleClickSpeed then
			-- double-click
		end
		GridX.CurLastTime = nCurTime
	end
	if e_Type == RIGHT_BUTTON_UP then
		-- right-click
	end
end

It takes care of the grid border (that ugly thing you have to mask out)
and makes sure that the header is ignored for the clicks.

nice going blue, thats better than my way, i put a hotspot over internal grid area and only fired the double click if "IsInRect" returned true for the hotspot, your way certanly is better :yes
