[Closed] listbox editable text fields

Feb 13, 2012 4:56 pm

Is there a dotnet item that allows users to double click and edit the displayed text in that cell?

I know there are work arounds such as creating a popup dialog with an edit text field and all that, it’s just annoying to do and I was hoping dotnet had something more simple.


(
	try (destroyDialog ::rlListBox) catch()
	rollout rlListBox "Drop Down List"
	(
		dotNetControl lbItems "System.Windows.Forms.ListBox" height:100 ItemHeight:10
		
		on lbItems SelectionChangeCommitted  e do
		(
			print "here it goes"
			fnUpdateList()
		)
		
		on lbItems doubleClicked itm do
		(
			lbItems.text = lbItems.items["cool"]
		)
		
		on rlListBox open do
		(
			lbItems.items.addrange #("nice","nice","nice","nice")
		)
	)
	createDialog rlListBox
)

it’s pain in the a$$ really. that’s why for this kind of interface solution i moved from listview to datagrid.

I used this: http://forums.cgsociety.org/showthread.php?p=4832734#post4832734

And modified it to get the bounds of the cell being clicked -- and replaced it with a .net textbox.  The textbox currently excepts esc or enter and then does some work to update the object model.

fn subItemAtMousePos lv =
    (
    	-- this has the potential to miss selecting an item that could cause an error... might as well ignore it and
    	-- let the user just double click again.
    	try
    	(
    		-- get mouseposition on screen
    		local pos = lv.mousePosition -- screen position
    		local posScreen = [pos.x, pos.y] -- need the screen position for placement of new edittext
    		
    		-- get dialog (specifically the LV) position information
    		pos = lv.PointToClient pos 
    		local posDialog = [pos.x, pos.y]
    		
    		-- get information for the listview item & subitem
    		local li = lv.getItemAt pos.x pos.y
    		local si = li.getSubItemAt pos.x pos.y
    		
    		-- Get the bounding box position.
    		local posBounds = [si.Bounds.X, si.Bounds.Y-2]
    		
    		-- do the math.  
    		posFinal = ((posScreen - posDialog) + posBounds)
    		
    		-- Get the indices for listview item index and the subitem index.
    		local idxs = #( li.index , (li.subitems.indexof si) )  
    		
    		--// debug print
    		print lv.Items.item[idxs[1]].subitems.item[idxs[2]].text
    		   
    		::g_tempEditTextBoxInfo = lv.Items.item[idxs[1]].subitems.item[idxs[2]].text -- I needed to add a global that the second rollout can read on create
    		createDialog NetTextBoxTest style:#(#style_sunkenedge) pos:posFinal modal:true -- make the dialog look integrated.
    		)
    	)
    	catch()
     )
