-==== size ==== +==== Size ====
-Plugins should be tested to still render fine in all panel sizes, starting from 16px to 40px at least.+
  
-The exception is a deskbar mode - it should look good when: +The panel can be made from 16px tall to 128px tall, multiplied by the amount of rows : that makes a lot of combinations to test when designing an UI for a plugin, and one should try to make its UI consistent and usable in most sizes.
-  * a single row is used - in such a case plugins should resort to displaying icons only. Plugins which must display text or input fields are exempt from this requirement. +
-  * look "reasonable" (look good but potentially skipping or clipping some labels) with number of rows equal to 3 and row size equal to 22px.+
  
 +==== Widgets padding/size ====
 +
 +Widgets padding/size is important for consistency :
 +
 +  * Plugins have to set their container border width with ''gtk_container_set_border_width()'' to 1px for a panel size < 26px and 2px otherwise. Adjust it in the ''size-changed'' callback, which is called anyway in the panel creation.
 +  * When displaying a frame around the plugin, the border has to be 0px for a size of < 26px and 1px otherwise.
 +  * Plugins can set a default spacing between children in the container via the //spacing// parameter to ''xfce_hvbox_new()''
 +  * Labels should be packed (via ''gtk_box_pack_start()'' or ''gtk_container_add()'') with a 2px padding.
 +  * Progressbars, images and buttons should be packed with a 0px padding
 +  * Progressbars should be 8px wide (when vertical, 8px tall when horizontal), use -1 for the other size to let the parent widget set the size.
 +
 +==== event box ====
 +If the plugin has an eventbox (to receive clicks or such), it should be made invisible to avoid problems with transparent/coloured panels. It should also be above its childs to actually receive events.
 +<code>
 +gtk_event_box_set_visible_window(GTK_EVENT_BOX(ebox), FALSE);
 +gtk_event_box_set_above_child(GTK_EVENT_BOX(ebox), TRUE);
 +</code>
