+Openbox also lets you pick what the small graphics in the buttons and in the manu look like. It uses the X Bitmap file format (.xbm extension). The style resources are as follows:
+.EX
+! Close, maximize, sticky and iconify
+! buttons on a window.
+window.button.close.mask: xbm file
+window.button.max.mask: xbm file
+window.button.stick.mask: xbm file
+window.button.icon.mask: xbm file
+
+! The icon for submenus in a menu.
+menu.arrow.mask: xbm file
+
+! The icon for a selected option or workspace
+! in the menus.
+menu.selected.mask: xbm file
+
+! The left and right buttons in the toolbar
+toolbar.button.left.mask: xbm file
+toolbar.button.right.mask: xbm file
+.EE
+If the xbm file value is the path to a .xbm image. If the value is absolute, it uses that file. If the file is just a file name, e.g. `close.xbm', it uses ~/.openbox/buttons/close.xbm.
