Text always selected in entry
Hi, GTK2: It seems that the default text in an entry is always selected when entering the field. How do I prevent that from happening. I've tried gtk_editable_select_region with start and end set to 0, but this does not help. Do someone have an idea about how I get past this problem? /Egon ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list

Immovable columns
Third attempt with this mail. There was some confusion with my email address coming out as [EMAIL PROTECTED] even though I set it to [EMAIL PROTECTED] If you get this multiple times then I apologise. --- Hi, I have a situation where I want to display data in a tree view and have the leftmost columns not scroll. e.g. I have five columns abcde with only four columns visible (abcd) pressing right on the horizontal scrollbar should scroll bcde, possibly by an entire column at a time. Giving acde visible. The rows are both affected by this and should scroll as normal. I can think of three possible means to achieve this: 1) Two tree views side by side One tree view contains the first column. The second tree view contains all other columns The horizontal scroll bar only affects the second view. The vertical scrollbar affects both view. I expect a single model should be fine for both views Does this seem plausible? Can I do this with the vertical scrollbar? 2) Sub-class the TreeView Add the ability to mark columns as fixed. The column must be either the leftmost column or right of a fixed column. Scroll left and right is then handled by re-ordering the columns. e.g. start with columns abcde with column a fixed press scroll right, columns are re-ordered to acdeb This would also achieve scrolling by a whole column at a time. This is probably the most work but might be useful to others. 3) Use GtkTable widgets instead Construct 2 GtkTable widget one for the fixed columns and one for the scrollable columns. This also requires implementing the headers separately as they don't scroll vertically but will scroll horizontally for the second table. This gives me complete control over construction but requires me to implement things I give more cheaply with a tree control. i.e. multiple views, searching, sorting, etc. Whichever option I choose I have a fair bit of work ahead. I'm early enough into the project that I can choose the least painfully route I hope. Any suggestions?

Can't correctly set data to an object (button)
Hi all,
Well I have toggle button to wich I attached a default string (DEFAULT)
using the gtk_object_set_user_data function.
In the callback toggle function I reassign this string regarding the state
of the button.
I pick up the new string from a gtk_entry.
The problem is when I get the attached data again, is not set to the rigth
value.
When I toggled the button:
- the printf(attached data 1 = %s\n,attached_data); shows the rigth
value.
- the printf(Active profile name = %s\n,profile_name); shows the rigth
value too.\
- the printf(attached data 2 = %s\n,attached_data); shows an unexpected
value DEFAULT
Just like below
attached data 1 = DEFAULT
Active profile name = CUSTOM
attached data 2 = DEFAULT
If on the line where I set the new string (
gtk_object_set_user_data(GTK_OBJECT (button),profile_name);)
I replace profile_name by a static string (i.e CUSTOM) it works.
Does someone can explain what is wrong in my code ?
Thank you in advance
