Region notes when using the border method in ext

When region is used, an error occurs, so I tested it myself.

Code:

Ext. onready (function () {var viewport = new Ext. viewport ({layout: 'border', // html: '<p> step 2, 4 in total </P>', items: [{region: 'north ', split: True, Title: 'north', // north, south, east, west or center) Border: true}, {region: 'west', split: True, title: 'west', border: true}, {region: 'center', split: True, Title: 'center', border: true}, {region: 'east', split: true, Title: 'east', border: true}, {region: 'south', split: True, Title: 'south', border: true}]}) ;});
 

According to the test results, we can see that the center cannot be empty, and other values can be empty without being set.

Check the API and have the following information:

Borderlayout is fixed and will not change or change the pattern after rendering. The central region is indispensable in borderlayout settings. If there is no other area, the central layout will be the whole area of the layout. The regions of a borderlayout areFixedAt render time and thereafter, no regions may be removed or added. The borderlayout must have a center region, which will always fill the remaining space not used by the other regionsInThe layout.
 

Summary:

1. center is required. (If ext can be located without the center, we hope it can be solved in the next version)

2. when using other IDES (for example, C #), you can use (top, left, right) and so on to locate the problem. It feels more convenient than the use direction. After all, it is more user-friendly, you do not need to go to the map (Upper North, lower south, left West, right East.
