There is sample code in the LangRef on how to do that conversion (look for SYSTEM.MOUSEX) _________________ Dave Sisemore MacPro, OSX Lion 10.7.4 RB2012r1 Note : I am not interested in any solutions that involve custom Plug-ins of any kind Top tfindlay Post subject: Re: Listbox highlight by mouse overPosted: Sun Sep 09, 2012 9:45 am Joined: Mon Oct 10, 2005 12:30 pm Posts: 140 Location: Keremeos, BC Canada Great, thanks! _________________ http://www.ttpsoftware.com Top tfindlay Post subject: Re: Listbox highlight by mouse overPosted: Sun Sep 09, 2012 10:17 am Joined: Mon Oct 10, 2005 12:30 pm Posts: 140 Location: Keremeos, BC Canada I can't seem to get it to work. In the listbox.open event I have Quote:me.AcceptRawDataDrop("text") In the dragover event I have Quote: dragRowNum = me.RowFromXY(x,y) dragOn = true In CellBackgroundPaint I have Quote: if dragOn = true then row = dragRowNum g.ForeColor = RGB(0,255,0) g.fillrect(0,0,g.Width,g.Height) end if Nothing happens when the dragItem is hovering over the listbox. _________________ http://www.ttpsoftware.com Top DaveS Post subject: Re: Listbox highlight by mouse overPosted: Sun Sep 09, 2012 10:26 am Joined: Sun Aug 05, 2007 10:46 am Posts: 4115 Location: San Diego, CA you are doing nothing that is forcing the listbox to redraw. in your dragover event do something like.. if dragrownum<>last_dragrow_num then last_dragrow_num=dragrownum listbox1.invalidate(last_dragrow,-1) ' check the syntax for this (off the top of my head) end if Note also.. you have nothing to RESET your color. the color of each box will change as the cursor goes over it.. but will not change back, unless you invalidate those rows again. _________________ Dave Sisemore MacPro, OSX Lion 10.7.4 RB2012r1 Note : I am not interested in any solutions that involve custom Plug-ins of any kind Top tfindlay Post subject: Re: Listbox highlight by mouse overPosted: Sun Sep 09, 2012 10:49 am Joined: Mon Oct 10, 2005 12:30 pm Posts: 140 Location: Keremeos, BC Canada After checking the LR I added this to the DragOver event Quote: if dragrownum<>last_dragrow_num then last_dragrow_num=dragrownum listbox1.invalidate end if It made no difference. _________________ http://www.ttpsoftware.com Top Lazze Post subject: Re: Listbox highlight by mouse overPosted: Sun Sep 09, 2012 11:20 am Joined: Thu Jul 27, 2006 7:32 am Posts: 102 Location: Esbjerg, Denmark Try using the "MouseOver" event and Listbox.RowFromXY Something like this in "MouseOver" row=me.RowFromXY(x,y) HighLight(row) Where "HighLight" is a method you have to code, which highlights the row "row" in your listbox _________________ Why make it simple if it can be made complicated? http://www.laniesoftware.com Top DaveS Post subject: Re: Listbox highlight by mouse overPosted: Sun Sep 09, 2012 11:54 am Joined: Sun Aug 05, 2007 10:46 am Posts: 4115 Location: San Diego, CA MouseOver is not what he wants..... as it fires regardless of the fact there is an object/text being dragged. I suggest that breakpoints be inserted (and or beeps) to insure that the events are evening happening... As in are you SURE you actually have TEXT in a DRAGITEM? plus you neglected your DRAGON flag.... it that is still in your PAINT event.. the event is firing... but fails the test. _________________ Dave Sisemore MacPro, OSX Lion 10.7.4 RB2012r1 Note : I am not interested in any solutions that involve custom Plug-ins of any kind Top Display posts from previous: All posts1 day7 days2 weeks1 month3 months6 months1 year Sort by AuthorPost timeSubject AscendingDescending Page 1 of 1 [ 8 posts ] -- Over 1500 classes with 29000 functions in one REALbasic plug-in collection.
