testing it on ubuntu 12.04 x64 PB 5.10
compiles in ascii mode and justifies the text
compiles in unicode doesn't justify the text, even when changing the Property to p-utf8

Code: Select all

 g_object_set_double(*Object, Property.p-Ascii, Value.d, Null) As "g_object_set"

thx

please, how to get around this problem or how to use a different code

gtk2-devel-2.18.9-10.el6.x86_64

@thierry94,
it would have been nice if you had posted a link to the thread from which you have copied my entire example code:
http://www.purebasic.fr/english/viewtop ... 31&start=8

I have tested my example code with PB 5.10 x64 on Kubuntu 12.04 LTS x64 and Ubuntu 12.04 LTS x64 with file format "Plain text" and "Utf8" and with Compiler Option "Create unicode executable" enabled and disabled. With all settings my example code works as it should and right justifies the first column. So sorry, that I can't reproduce your problem and be of any help...

@idle,
I don't understand why the right justification of the first column doesn't work on your Ubuntu 12.04 x64 when testing with Unicode. I can't reproduce your finding on Ubuntu 12.04 x64 and PB 5.10 x64...

I don't know why it's failing in unicode mode on my system.
The only way I can get it to work is changing the import to a *property.p-ascii
and poking the xalign

I'm using a clean install of PB 5.10 final

Code: Select all

 If *CellRenderers
          Count = g_list_length_(*CellRenderers)
          len = Len("xalign")
          *str = AllocateMemory(Len)
          PokeS(*str,"xalign",len,#PB_Ascii)
          For i = 0 To Count - 1
             g_object_set_double(g_list_nth_data_(*CellRenderers, i),*str, AlignmentFactor, #Null)
          Next i         
         FreeMemory(*str)
          g_list_free_(*CellRenderers)
        EndIf

i have found

i have replaced

Code: Select all

 g_object_set_double(g_list_nth_data_(*CellRenderers, i), "xalign", AlignmentFactor, #Null)

by

Code: Select all

        *Cellule.GtkCellRenderer = g_list_nth_data_(*CellRenderers, I)
        *Cellule\xalign=AlignmentFactor

Who knows why is not aligned text in columns or how to do it? in linux.

Posted: **Fri Mar 25, 2016 2:20 pm**

I found the cause of.

Code: Select all

ImportC ""
        gtk_tree_view_column_set_alignment(*tree_column, xalign.f);             replaced PureBasic's V5.* buggy: gtk_tree_view_column_set_alignment_(*Column, Alignment)
      EndImport

Now it is necessary to size an item avtosize
