Textbox

Contents |
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.
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.
readonly
Values: Y, N.
default
Values:
- blank
- constant
- value that comes from DB or memory
