I discovers a strange behavior in my project:
the displayed number of columns in the Listbox is fewer than it appears.
This bother me since ages, but I do not always saw it, and so it is just now that I really can say there is a bug.
A bug ? Yes, but how can that be ?
And, better, how can I know were (more or less) I see a bug ?
In fact, I just issued a cmd-a followed by a cmd-c, a click in the main window and a cmd-v: I get all my columns I do not saw in the original window *.
I cannot be angry because I wanted to reformat the whole decoding code / window design because of that. Fortunately, I discovers this special feature some minutes ago.
Now, I am asking myself what the bug can be. A REAL bug in Xojo ? I cannot believe that since the Listbox control is so widely used. A bug in my code ? Why not (probably), but how can this be ?
Even when I enlarged (zoom) the window, I only get the same number of columns. BTW: I do not told you that I have the last, rightmost Columns. The missing Columns are before the last one.
Is it possible that those columns have 0 as Column width ? No (after making some tests): I have the item size and item extension column headers, but they are empty. I am totally out of ideas. I will get an eye on the code used to parse the item names, etc. but I cannot believe what I wrote above; still, I will check just in case.
The code seems to be OK. I added the loop below to be sure about the columns widths (I set them to 50 pixels):
[code] Dim Loop_Idx As Integer
For Loop_Idx = 0 To LB.ColumnCount
LB.Column(Loop_Idx).widthExpression = “50”
If UserCancelled Then Exit
Next[/code]
Just in case: there are only 10 (or 11 ? I am unsure) columns (10 defined headings plus one empty column with a vertical separator without a Heading string and a large white on the right of the Listbox (well know bug). Even when I resize the window, the contents of two empty Columns is not displayed, but present.
The “missing” contents columns are updated when I set all columns to max width
Did I told you that this behavior is also present under Windows 10 (in a real PC, current with this week updates).
I also forgot to give the tests conditions:
El Capitan .6,
Xojo 2015r1,
MacBook Pro was shutdown, then after some minutes, a boot.
Internet was OFF.
No other open Application.
A nap is welcome -{
Idea(s) ?
- In that window, I take a folder (directory) as a source, take all items found there, decode the items names and place them into the Listbox columns. I also take the file extension, file size and some more stuff.
