generic-canvas.map XML:
|
||
|
|
- to be used by dialogs and instruments to add a generic map (navaids, fixes, airports etc)
|
||
|
|
- with each feature put on a separate layer (canvas group)
|
||
|
|
- each layer being controllable via a boolean property
|
||
|
|
|
||
|
|
NOTE: This is still work in progress, and will be significantly refactored in the time to come
|
||
|
|
|
||
|
|
Current requirements: (these are subject to change)
|
||
|
|
|
||
|
|
Dialogs wanting to use this, MUST:
|
||
|
|
|
||
|
|
- set DIALOG_CANVAS in open block
|
||
|
|
- provide a helper function dialog_property(p) to return a property appended to the dialog root in /sim/gui/dialogs/FOO/
|
||
|
|
- to set up layer-checkboxes automatically, use canvas.GenericMap.setupGUICheckboxes(DIALOG_CANVAS, gui_group)
|
||
|
|
|
||
|
|
For example, add this to your dialogs Nasal/open block in "foo.xml":
|
||
|
|
var dialog_name = "foo";
|
||
|
|
var dialog_property = func(p) return "/sim/gui/dialogs/foo/"~p;
|
||
|
|
var DIALOG_CANVAS = gui.findElementByName(cmdarg(), "airport-selection");
|
||
|
|
canvas.GenericMap.setupGUICheckboxes(DIALOG_CANVAS, "canvas-control");
|
||
|
|
|
||
|
|
TODO: use a single "InitCanvasMapSupport();" helper
|
||
|
|
|
||
|
|
In the close block, you'll want to call "map.cleanup_listeners()" at the moment
