Binding Images in Controls

[Trenloe]

You need to give us a more information - like some code you're actually using - maybe a skeleton extension or something we can play with to get it working. At the moment you're drip feeding us information and it's impossible for us to give true guidance.

The code I'm using looks nearly identical to the reference manual code Moon pointed to earlier in this thread. It would be very difficult to make a skeleton extension, but possible. But here is the code that it used here; not much to really look at.

function embedImage(dropNode)
	local win = createWindowWithClass("imageryTest", "id-00002");
	local ctrl = win.createControl("imagery", "image");
	local w, h = ctrl.getImageSize();
	Debug.console("getDatabaseNode()");
	Debug.console(getDatabaseNode());
	Debug.console("win.getDatabaseNode()");
	Debug.console(win.getDatabaseNode());
	Debug.console("win.children");
	Debug.console(DB.getChildren(win.getDatabaseNode(), ""));
	Debug.console("ctrl");
	Debug.console(ctrl);
	Debug.console("starting w");
	Debug.console(w);
	Debug.console("starting h");
	Debug.console(h);
end

The 'imagery' template is a clone of the reference manual image template:

	<template name="imagery">
		<imagecontrol>
			<anchored position="insidetopleft" />
			<indicators availability="blank" locked="blank" loading="blank" zoom="blank" shortcuts="blank" />
			<invisible />
			<disabled />
		</imagecontrol>
	</template>

Assuming your image is stored in the campaign database at image.id-00002 ? i.e. It is a normal campaign image?

Then your createWindowWithClass("imageryTest", "id-00002"); needs to refer to image.id-00002, that is: createWindowWithClass("imageryTest", "image.id-00002");

This is what I was trying to point out before.

Just using "id-00002" for the image database reference will create a DB node at id-00002 in the XML root, because this is an absolute database node identifier. Check your campaign XML, I bet you'll see a DB node of "id-00002" right off the root.

I'm guessing you're getting confused between relative and absolute database references? See "Node Identifiers" here: https://www.fantasygrounds.com/modguide/database.xcp

[Trenloe]

Or, if you want to use a relative identifier put a period in front: createWindowWithClass("imageryTest", ".id-00002")

This will reference a db node relative to the <datasource> of the windowlist. For example, if the windowlist has <datasource>image</datasource> then using ".id-00002" (a relative identifier) would reference image.id-00002 as the absolute database identifier (which I believe is what you need).

Yes it is.

This is interesting. It's not how the wiki describes the behavior of the <datasource> of a window. According to it the datasource of a windowlist or subwindow is automatically relative.

A database identifier forming the base from which the actual data source is derived. For top level windows the identifier is relative to the root node of the database, for subwindows and windowlists it is relative to the containing control.

Or, if you want to use a relative identifier put a period in front: createWindowWithClass("imageryTest", ".id-00002")

This will reference a db node relative to the <datasource> of the windowlist. For example, if the windowlist has <datasource>image</datasource> then using ".id-00002" (a relative identifier) would reference image.id-00002 as the absolute database identifier (which I believe is what you need).

I'll try this.

EDIT: Yeah, it seems to be getting to the image now. It would seem I was misled by the description of the <datasource>...

[Trenloe]

Yes it is.This is interesting. It's not how the wiki describes the behavior of the <datasource> of a window. According to it the datasource of a windowlist or subwindow is automatically relative.

Controls are relative to the window they are in, that's what this is referring to.

LUA coding is usually different.

Your debug commands you listed a few posts back were eluding to this.

[Nickademus]

Yeah, sometimes it feels like I'm grasping at straws using the wiki.

[Trenloe]

The command you used is here: https://www.fantasygrounds.com/refdo...indowWithClass It specifies "The data node identifier path..." - these are documented under "node identifiers" here: https://www.fantasygrounds.com/modguide/database.xcp Your debug statements were pretty much telling you that you weren't accessing the right nodes and going to a root of "id-0002" rather than "image.id-00002", as I eluded to also. Believe what they were telling you, rather than second guessing!

[Nickademus]

Then your createWindowWithClass("imageryTest", "id-00002"); needs to refer to image.id-00002, that is: createWindowWithClass("imageryTest", "image.id-00002");

Changed to this and it works fine. The image is showing up where and I it's supposed to. Switch over to the local client and the same lua file code throws a console error:

createWindowWithClass: Unable to create target named node

Is there some aspect of a windowlist that doesn't allow players to do things? I didn't see any such note in the windowlist description. Too tired to fool with it more tonight...

More than likely the image hasn't been shared with the player, so it can't be accessed. Either share the image or make it public using code on the GM side: https://www.fantasygrounds.com/refdo....xcp#setPublic
