Pseudo selectors

Pseudo selectors can be used to apply only when some conditions are fulfilled.

Pseudo selectors are preceded with a colon and can be combined. When combining several pseudo selectors, the style will be applied if all pseudo selector conditions are fulfilled.

<Style name="Table:even:input" >
<Style name="Edit:focus" >
<Style name="Edit.important:focus" >

Pseudo selectors have different priorities; the style with the most important pseudo selector will be used when several styles match.


focus
query
display
input
even
odd
inactive
active
message
error
summaryLine

Table 1. Pseudo selector description and priorities
Priority	Pseudo selectors	Condition
1	focus	The widget has the focus
2	query	The widget is in construct mode
3	display	The widget is in a display array
4	input	The widget is in an input array, input or construct
5	even	This widget is on an even row if an list (Table or Tree)
6	odd	This widget is on an odd row if an list (Table or Tree)
7	inactive	The widget is inactive
8	active	The widget is active
9	message	Applies only to text displayed with the `MESSAGE` instruction
10	error	Applies only to text displayed with the `ERROR` instruction
11	summaryLine	Applies only to text displayed in `AGGREGATE` fields of tables

Pseudo selectors also define the priority of your styles. A more generic style will be used when the pseudo-selector has a higher priority.

For instance: you want all important edits to have red text, but you want the current field to be displayed in blue:

<Style name="Edit.important" >
<Style name=":focus" >

The style ":focus" is more generic than "Edit.important"; therefore, it will be used for the focused item, as the pseudo selector is more precise.
