Is it possible to use arrow keys alone to expand tree node in package explorer in Eclipse on Linux?
Put this into your ~/.gtkrc-2.0
and you should be good to go. The Left and Right lines make the requested change, the rest are just my personal additions to make the tree-view act more vim-like. Hope that helps!
binding "gtk-binding-tree-view" { bind "j" { "move-cursor" (display-lines, 1) } bind "k" { "move-cursor" (display-lines, -1) } bind "h" { "expand-collapse-cursor-row" (1,0,0) } bind "l" { "expand-collapse-cursor-row" (1,1,0) } bind "o" { "move-cursor" (pages, 1) } bind "u" { "move-cursor" (pages, -1) } bind "g" { "move-cursor" (buffer-ends, -1) } bind "y" { "move-cursor" (buffer-ends, 1) } bind "p" { "select-cursor-parent" () } bind "Left" { "expand-collapse-cursor-row" (0,0,0) } bind "Right" { "expand-collapse-cursor-row" (0,1,0) } bind "semicolon" { "expand-collapse-cursor-row" (0,1,1) } bind "slash" { "start-interactive-search" () }}class "GtkTreeView" binding "gtk-binding-tree-view"
then restart your Eclipse to apply new bindings
If anyone is wondering how to do this with GTK3 - simply open ~/.config/gtk-3.0/gtk.css
and add the following:
@binding-set MyTreeViewBinding{ bind "Left" { "expand-collapse-cursor-row" (0,0,0) }; bind "Right" { "expand-collapse-cursor-row" (0,1,0) };}GtkTreeView{ gtk-key-bindings: MyTreeViewBinding;}
My version for GTK3 that behaves in more natural way.Add the following to ~/.config/gtk-3.0/gtk.css:
@binding-set MyTreeViewBinding{ bind "Left" { "select-cursor-parent" () "expand-collapse-cursor-row" (0,0,0) }; bind "Right" { "expand-collapse-cursor-row" (0,1,0) };}GtkTreeView{ gtk-key-bindings: MyTreeViewBinding;}
