I do not have the sources with me right now, but I saw a wrong result in an application. I used g.StringWidth, etc. to get a ListBox column width / Set LB.ColumnWidths… An entry had non ASCII characters in it and that column width is incorrect. The entry is: \ (without \< and \>) Do we know this (as a bug) ? (27 entries returned by Feedback; search strins is “StringWidth”.) Notes (after checking docs): I certainly use Integer instead of Double. MacBook Pro 2011-11 OS X 10.9.5 Xojo 2014r2.1 ---

I just built a small test project that measures strings entered in a TextField and reports the StringWidth. “ete” and “t” give exactly the same stringwidth. Please to be more specific. ---

I used curly quotes (start-end). These are not in the ASCII values (0-127). To be sure of what I say, copy / paste the text in the question (far above) into Apple’s TextEdit and resize the text to say 36 and you will see what I wanted to tell. My glasses needs to be improved, so I just do that in case I’ve made a mistake. On a second click (several minutes after, searches on [www.cbs.com](http://www.cbs.com), save data, etc.), and a manual resize, another click in the resize button shows a different behavior. So, now, I do not know. I know: I close the window but keep the application running, I re-open the window, I open the original text file, I clicked in the ToolBar’s Resize Columns button and I get the same behavior. Worst, this also does not fit in the new column size: Les vieux he?ros ne meurent jamais The displays stop at “jama” leaving “is” lost in the space/time warp ! ete and été: try in a ListBox and with a far larger string like “La chanson de l’été dernier…” and you may see a discrepancy. All of this is really queer. ---

I do not closed the window, but I changed the first column contents from an acronym to its full name, then I re-open the newly modified file and the ListBox width resize do correctly its job. BTW: the other word to say Strange (last word of my previous entry have been changed. Why ? That word is Q-U-E-E-R (Queen with an ending r instead of an ending n). I found that word in some comic strips / newspaper of the 1930s and checked its meaning with Systran (I think). ---

Back to your current issue of stringwidth, I cannot verify what you report. With Arial at point 36, ete or été = 50.04492 La chanson de l’ete dernier… or La chanson de l’été dernier… = 470.3027 My test program is awfully simple : - One TextField set to Arial, 36 points - OneTextArea for the results - In the TextField : `Function KeyDown(Key As String) As Boolean if key = chr(13) then dim p as new picture(me.width,me.height,32) p.graphics.textfont = me.textfont p.graphics.textsize = me.Textsize TextArea1.text = TextArea1.Text+str(p.graphics.stringwidth(me.text))+EndOfLine return true end if End Function ` Are you sure you are setting the same textfont and textsize for the listbox as for stringwidth ? Are you using System ? If so, you may want to switch to Arial (cross platform). ---

> same textfont and textsize for the listbox as for stringwidth > I probably used ListBox Text Size and ListBox TextFont. Used font: probably system. > you may want to switch to Arial > Good idea. Don’t shake your head. I will watch that carefully this afternoon with the project and after a shutdown / clean boot. I have some troubles with the rtf load (tabs are different from Apple’s TextEdit). I used declares to display those RTF files. ---

Here are the answers to the previous questions in the following code: [code] // a. Get the number of Rows & Columns ColCnt = LB.ColumnCount - 1 RowCnt = LB.ListCount - 1 ``` // Get the selected Font Name & Size FontName = LB.TextFont FontSize = LB.TextSize // Get a new Picture PictTmp = New Picture(600,40) // Set the default Text Font & Size PictTmp.Graphics.TextFont = FontName PictTmp.Graphics.TextSize = FontSize // b. Loop thru all Columns For ColIdx = 0 To ColCnt For RowIdx = 0 To RowCnt // Get one Cell contents CellStr = LB.Cell(RowIdx,ColIdx) // Get the width of the Cell String CellWidth = PictTmp.Graphics.StringWidth(CellStr) + 10 // Get the highest width ColWidth = Max(ColWidth,CellWidth) // Clears some variables CellStr = "" Next // Row Count[/code] ``` Note: `PictTmp = New Picture(600,40) `Yes, I know I can use `PictTmp = New Picture(0,0)`… Note also that I add 10 pixels to the cell width ! PS: I do not have faith in Phantom or Ghost (Who Walks or fly), but sometimes I deep ly wonder… PPS: Michel, don’t you recall the piece of code that was shared lately in this forum ? (I wrote mine sometimes earlier, but I could use that one) At last: I never clears any cache or whatever file between compilations. This may explain that ? ---
