Intro

Easily most used UI control.

Used to enter text on forms.

Major Attributes

type/format

Type as in "data type".

This encompasses "constraints". Normally system validates these.

Possible values - see Datatypes.

In ZK there are seperate widgets for some datatypes: "intbox", "decimalbox", etc.

! This could/should be defined often "before" the UI - this is a property of class of corresponding object. So in this case link should be provided instead of repeating definition.

validation

This relates to how / when we validate type/format.

Possible values:

  • stopOnMax - system will not let user enter more than X chars, it will simply silently stop as if we hit the wall
  • zk validation - typical "real-time" ZK validation - on focus Off bar will appear with "x"
  • on Submit - validate only after user clicked "Submit button". Standard Error pop-up will appear.


width

Defines how wide is a textbox on the screen.

Most of the times it is defined in number of chars (ZK cols attribute). But it could be also defined in pixels (ZK width attribute).

This is actually almost only style / layout issue, could be defined in Style section. So in this case link should be provided instead of repeating definition.


readonly

Values: Y, N.

default

Values:

  • blank
  • constant
  • value that comes from DB or memory

Template for spec
