Overriding WindowClass instance attributes from LUA

[xelab]

Hi,

is it possible to change some attributes (e.g. title) of the Window instance from within LUA? Since the change should be dynamic, I do not want to create separate new window templates.

Here is an example of what I am trying to do:

	<windowclass name="some_window_class" merge="join">
		<script>
			function onInit()
				Debug.chat("  onInit() called");
				
				
				------     I would like to change the title of this window instance (depending on some logic)
				
				
			end
		</script>
	</windowclass>

Thank you in advance

Well, first, you need to call any base window onInit call. Then, it depends on the window class and templates/names being used for that ruleset.

For most windows in the 5E ruleset (but not all), it could be as simple as:

    function onInit()
        if super and super.onInit then
            super.onInit();
        end
        title.setValue("My Custom Window Title");
    end

Amazing, this works perfectly.

However now I am stuck trying to access subwindow elements of the current window.

EDIT: Figured it out myself: elements of subwindow can be accessed via in the case below "subwin.subwindow.element_name"

	<windowclass name="main_window_class">
		<sheetdata>
			<subwindow_record name="subwin">
				<class>subwindow_class</class>
				<activate />
				<fastinit />
			</subwindow_record>
		</sheetdata>
	</windowclass>
	
	<windowclass name="subwindow_class">
		<sheetdata>
			<header_column name="element_name">
				<static textres="text_to_be_changed" />
				<center />
			</header_column>
		</sheetdata>
	</windowclass>
