Function isChangeDisabled

isChangeDisabled(): boolean
JMap.Project.isChangeDisabled

Returns true if the project change has been disabled by startup option "disableProjectChange" (see JCoreOptions).

Notice that as long the first project has not been loaded, this method returns false even if the parameter is true.

It becomes true, if option "disableProjectChange" is set to true, and a project has been activated.

Returns boolean
Example
```
// We assert that :
//  - the option "disableProjectChange" is true
//  - no project is yet activated, no map is displayed.

// returns false
JMap.Project.isChangeDisabled()

// first time a project is activated
JMap.Project.activateByName("My project")

// returns true
JMap.Project.isChangeDisabled()
```
