I tested the new column-resizable <tree> option, but could not get it to work.
I wonder, does this option require gtk3?

Hi Sigmund

Try column-resizeable. I've checked that it works in both gtk2/3 and it does.

Let me know how you get on because I can tweak things to a degree.

Okeeey, I see
...It works how you intended, but not the way I expected....
The column is now not resizable, but it still auto-widen the column to fit content. As I understand it, gtk-tree-view-columns-autosize should handle this, - not the resizing done by the user.

This example should explain the difference between <tree> and <table>

@Sigmund

These are the column properties but you can't set them, I have to create custom tag attributes for them:
https://developer.gnome.org/gtk2/2.24/GtkTreeViewColumn.html#GtkTreeViewColumn.properties

I'll have a play with them and see if I can set the width by column header label rather than the contents of the row, or simulate it somehow.

Cheers

I am hoping for the best.
This might sound like a minor issue, but the fact is that this behavior makes pMusic still choose <table> over <tree>. And keep in mind that using the <tree> widget would give icons, doubleclick and a right-click menu.

It must be mentioned that a secondary solution would be to update column width when the <tree> widget is updated. - So that the column width decreases if content has become narrower.


Thank you for your effort!

column-width works great
Thanks a lot


pMusic 4 - here we go

In revision 512:

column-sizing="mode|mode|mode|...".

This is a combination of the sizing and width properties:

• If mode is 0 or "" then column grows as default (GTK_TREE_VIEW_COLUMN_GROW_ONLY)
  
• If mode is 1 then column autosizes i.e. grows and shrinks (GTK_TREE_VIEW_COLUMN_AUTOSIZE)
  
• If mode is >= 2 then column width is fixed to the value in mode (GTK_TREE_VIEW_COLUMN_FIXED)
  

Cheers,
Thunor

[EDIT] You posted just before I pressed Submit. I've tweaked it in r511. Anyway, I'm glad it works

Also, "Please note that GTK_TREE_VIEW_COLUMN_AUTOSIZE is inefficient for large views, and can make columns appear choppy".

I haven't documented it yet, wiki/reference update to follow.

[EDIT2] I've renamed it to column-sizing in r512 because it makes more sense naming it that way around.

Great stuff, just a 'minor' issue...
Using single-click runs <action> when resizing column width.
Example should explain:

murga-linux is alive! https://webchat.freenode.net/?channels=puppylinux was fun though

pMusic will resize column-width nicely, as I have settled on selection-mode="3" for mulitple selections. But, it would also take benefit of a signal="button-release-event" (left-click) if that was possible without interfere with resizing column-width.

My problem is that that's the way the widget is made and there's nothing that I can adjust anywhere.

In gtkdialog, when a widget is created it results in a widget pointer which is stored in an array. Signals are then connected-up, some unique to the widget plus many common signals which are actually part of the base class GtkWidget. The button-release-event signal is simply coming from the tree (GtkTreeView) widget (it's connected to the tree widget's pointer) and I can't modify where it gets emitted from.

Let me know how you get on. Maybe you're already doing it differently now.

Nothing to bother about. Everything is working properly.


Thank you a lot for your cooperation!
