Using ZK Border Layout
Suppose in our shopping cart application, we have the following requirements:
- Product View - A table displaying the available products to purchase
- Shopping Cart View - A list of items placed in the shopping cart
- Order View - A record of all the orders placed
A Quick Intro to Border Layout
The borderlayout divides a page into five sections: North, East, Center, West, South.
The attributes involved in the configuration of border layout is listed in the table below:
| Attributes | Sample | Description |
|---|---|---|
| size | <north size="20%">...</north> <south size="180px">...</south> | set size in pixels or a percentage relative to its parent component |
| border | <east border="normal">...</east> | show/hide border; "normal" shows border, while "none" hides border |
| collapsible | <west collapsible="true">...</west> | allow the whole division to show/hide |
| maxsize/minsize | <south splitter="true" maxsize="500px" minisize="200px">...</south> | set the maximum and minimum allowable size for a component; |
| splittable | <north splittable="true">...</north> | allow the contents area size to be adjustable |
