[solved] two [grid] tags

[ZombieKnight]

Hi
Can I put two [grid] tags insto my custom dialog?
(So they are on top of each other)

[Celtic_Minstrel]

That's what [stacked_widget] is for.

Thanks!
I can't find it in wiki...

Your installation should have data/gui/widget/addon_list.cfg which uses it.

It looks like a stacked_widget contains layers, and each layer is something that looks like a grid.

[Celtic_Minstrel]

The default mode of a stacked widget is to stack its layers on top of one another. A lot of actual uses of it instead use it as a way to swap between different layers, showing only one layer at a time. I'm not sure if there's an example of its intended use in mainline. On the other hand, it's probably easier to use it that way compared to most of the mainline uses anyway.

What do you mean?
I have my add-on om different place.

I mean relative to wherever you have wesnoth installed. For example

Code: Select all

/usr/share/games/wesnoth/1.16/data/gui/widget/addon_list.cfg

If you're using linux and have mlocate or plocate installed, you could just do

Code: Select all

$ locate addon_list.cfg

Ok, where should I look for examples?

Do you have any examples of it being used?

Looking at the public member functions I think I have an idea of more or less what should be supported by the API. I tried wesnoth.print_attributes(), but I'm dumping core at the moment.

[Celtic_Minstrel]

I'm not aware of any examples of it being used outside of mainline. In mainline it's used in the following windows:

addon_list
mp_create_game
addon_manager
campaign_dialog
campaign_difficulty
game_stats
game_version
mp_create_game
preferences
server_info
story_viewer
title_screen

It's also used in a number of others for a hack that forces a widget to have a minimum size (that is, to prevent a widget from getting any smaller than the specified size). There's a macro in core that implements this hack, GUI_FORCE_WIDGET_MINIMUM_SIZE.

How do you show two layers at once?
Putting there:

Code: Select all

		T.grid {
			T.row {
				T.column {
					T.stacked_widget{
						id = "narration",
						definition = "default",
						T.layer{...},
						T.layer{...}

Shows only the first defined layer

That sounds like exactly what I wanted it for. I was thinking if I used blank.png scaled to some size one on layer, then my actual data (on a different layer) couldn't be shrunk to near useless by another row which I can't seem to stop from growing out of control (described as issue#2 at):

viewtopic.php?t=58000

I'll have to look into that macro and see if I can do anything with it.

I found .cfg files that use stacked_widget, but I was hoping to find corresponding lua files that manipulate the widget so I could determine of its properties (select_layer(s), layer_selected, etc).

That's what I'm looking for... how to select layers?

I don't know, but I did figure out that

dialog.narration.selected_index=2

would cause it to display your second layer INSTEAD of the first.

And now I'm wondering if you can use something like dialog.narration:add_item() to add layers. Completely off topic, but I either mess with that or mow the lawn.
