 ==== Size ==== ==== Size ====
  
-Two category of sizes can be distinguished for the panel: small and large size.+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.
  
-=== Padding ===+==== Widgets padding/size ====
  
-  * Plugins that include a padding have to stick to 1px for a size < 28px and 2px otherwise. +Widgets padding/size is important for consistency : 
-  * When displaying a frame around the plugin, the padding has to be 0px for a size of < 28px and 1px otherwise.+ 
 +  * 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);
