Hello,
please have a look at the Grid sample. When I append a column the CalcColumnWidth method returns the width of the new column. But unfortunately it is too small on XP with enabled visual styles and normal font size. I have to add another 15 pixels to make the full title visible. Does this depend on OS and Visual Styles?
Fred
The MSDN documntation mentiones that "The returned width takes into account the control's current font and column margins, but not the width of a small icon." Does that explain the difference you're seeing?
Hello, Owen, unfortunately it does not explain it in detail or I didn't understand quite well.

There is no icon the column header?!

I think the problem has no easy solution, other than to always add 12 or so pixels to the result. CalcColumnWidth calculates the minimum width of a column in he list control, but this is not necessarily the minimum width needed for the same text in the header control. I think the platform and control version could all affect the minimum width needed, but probably the only way to do it is to add a fixed number of pixels plus the image width if there is an icon.
I changed the code int he Grid sample to the following, and it seems to work on my Windows 7 system:
(Setq cWidth (+ (dcl_Grid_CalcColWidth GRID_Dcl-1_grid1 txt) (if (>= cImg 0) 48 12)))
Using the same subject.
Was a ToolTip already included to show larger texts than the field in Grid?
Thanks,

I've added that for Alpha 19.

Owen, I 've uploaded new DEU grid sample files. We had a test on Win XP, Vista and Win7. We've found out that it must be added another 15 pixels using VisualStyles and normal system fontsize with wndows default font.
I also changed the icon size to 16x16 because sometimes the column icon is larger than the height of column header. That looks not nice so I decided to resize.
