Class Description: This class is expected to render the application container and create the workspaces configured as per the meta data.
Called By: cbx canvas.core.WSManager
Meta data to be considered: ct canvas.metadata.getWorkspaces() → Returns an array of configured workspaces. The application container has to have that many child items as the length of this array
...
APIs to be supported: NA
Registry Signature:
| Code Block | ||
|---|---|---|
| ||
CLCR.registerCmp({'COMP_TYPE':'APPLICATION_CONTAINER'}, <<Application container class>>); |
Scope: The core layer passes on view port container element to this class, so that it does not have to query the DOM to get the parent element on which it has to be appended.
Sample Code Snippet:
| Code Block | ||
|---|---|---|
|
...
canvas.lib.ApplicationContainer = Class( |
...
canvas.core.Component, { |
...
layoutManager: '', |
...
constructor: function(config) { |
...
this.wsManagerConfig = config; |
...
canvas.lib.ApplicationContainer.$super.call(this); |
...
this.createItems(); |
...
}, |
...
createItems: function() |
...
{ var appContainerConfig = { "eleType":"div", |
...
"id":"application-container" |
...
}; |
...
var appContainerObj = new |
...
canvas.lib.layer(appContainerConfig).getLayer(); |
...
this.addItem(appContainerObj); |
...
delete appContainerConfig; |
...
// Start process of creating the workspace and layout var wsContainerConfig; var wsArr = canvas.core.ws.metadata.getWorkspaces(); |
...
canvas.lib.workspacehandler.createWorkspaces(wsArr,this); |
...
}, |
...
// |
...
Return the object of app container containing the workspaces |
...
getAppContainer: function() |
...
{ return this.getItem(0); |
...
} |
...
}); |
...
CLCR.registerCmp({'COMP_TYPE':'APPLICATION_CONTAINER'}, |
...
canvas.lib.ApplicationContainer); |
It has to be noted in the above snippet that cbxcanvas.lib.workspacehandler.createWorkspaces() is a utility API which creates the workspace elements for the array of the workspaces passed, and finally appends to the parent element. Here is what this utility API is supposed to do.
| Code Block | ||
|---|---|---|
| ||
var workspaceContainerConfig = { |
...
"eleType": "div", |
...
"id" : wsArray[index].WORKSPACE_ID, |
...
"class": "workspace "+wsArray[index].WORKSPACE_ID, |
...
"style": |
...
{ "display":"none" |
...
} |
...
}; |
...
var wcContainerObject = new |
...
canvas.lib.layer(workspaceContainerConfig).getLayer(); |
...
$(this.appContainer.getItem(0)).append($(wcContainerObject)); |
The following code snippet shows the usage of workspace selection handler:
| Code Block | ||
|---|---|---|
| ||
activateWorkspace: function(workspaceId,index,callBackFn,scope) { |
...
callBackFn = |
...
canvas.isFunction(callBackFn)?callBackFn: |
...
canvas.emptyFn; |
...
scope = scope?scope: this; |
...
var config = |
...
{ WORKSPACE_ID:workspaceId, |
...
SYSTEM_WORKSPACE_IND:SYSTEM_WORKSPACE_IND |
...
}; |
...
// Pre workspace activate operations here canvas.core.ws.metadata.getWorkspaceManager().wsSelectionHandler(config,null,function(wsContainer) |
...
{ // Post workspace activate operations here },scope); |
...
} |
