Condition UI directives

These directives are a series of traits that performs condition operations on an element in a user interface XML block. These are typically used after all the needed mathematical operations (Mathematical UI directives) in a block to set a condition on when are these operations run.

• Eq - performs an operation when its value is equal to the value of the variable.
• Neq - performs an operation when its value is not equal to the value of the variable.
• Gt - performs an operation when its value is greater than the value of the variable.
• Gte - performs an operation when its value is greater than or equal to the value of the variable.
• Lt - performs an operation when its value is lower than the value of the variable.
• Lte - performs an operation when its value is lower than or equal to the value of the variable.
• Onlyif - performs an operation when its value is true.
• Onlyifnot - performs an operation when its value is false.

Example

 <onlyif> <copy src="me()" trait="mouseover"/> <eq> 3 </eq></onlyif>
