[solved] two [grid] tags

[ZombieKnight]

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.

...
I want to show both layers at the same time (over each other)

[white_haired_uncle]

I was able to get two layers to show on top of each other by setting both of the widgets visible:

Code: Select all

function wesnoth.wml_actions.stacked_widget_gui()
        local dialogDefinition = {
                wml.tag.tooltip { id = "tooltip_large" },
                wml.tag.helptip { id = "helptip_large" },
                wml.tag.grid {  wml.tag.row { wml.tag.column {
                        wml.tag.stacked_widget {
                                id = "stacker",
                                definition = "default",
                                T.layer {
                                        T.row { T.column { T.label { id="my_label1",label = "Hello world" } } } 
                                },
                                T.layer {
                                        T.row { T.column { T.label { id="my_label2",label = "Goodbye, cruel world" } } }
                                }
                        }
                } } } 
        }

        local function preshow(dialog)
                dialog.stacker.my_label1.visible = true
                dialog.stacker.my_label2.visible = true
        end
        gui.show_dialog(dialogDefinition,preshow)
end

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).

Those don't exist. All core widgets are handled in C++.

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

dialog.narration.selected_index=2

I'm not 100% sure but I think setting it to 0 or -1 might make it show all layers.

And now I'm wondering if you can use something like dialog.narration:add_item() to add layers.

Unfortunately, add_item is only implemented for listboxes. It probably isn't reasonable for this to be a feature request either, as each layer has a unique definition. It might be reasonable to request support for stacked widgets in add_item_of_type though.

[ZombieKnight]

Code: Select all

dialog.narration.selected_index=2

works... setting it to 0/-1 results in seeing only first layer.

[ZombieKnight]

Yup,

Code: Select all

dialog.narration_stacked_widget.narration_title.visible = true
dialog.narration_stacked_widget.test_text.visible = true

works...
THANKS SOOO MUCH for the help <3
...
I've got stuck again
That's my whole code, it's a weird thing the last T.layer does...
hopefully, my code will be readable

Code: Select all

		maximum_height = "(screen_height - 30)",
		maximum_width = "(gamemap_width)",
        horizontal_placement = "left",
        vertical_placement = "bottom",
		vertical_grow = true,
		T.grid {
			T.row {

							}
						}
					}
				}
			}
		}
	}
	local function narration_preshow(dialog)

		--gui.show_dialog( narration_help, narration_help_preshow, narration_help_postshow ) --two dialogs
	end
	local function narration_postshow(dialog)

	end
	-- close_func = function close_dialog(dialog)
	-- 	dialog:close()

... That monstrosity is my code...
Why is my T.text_box in the screen center(tho it's defined to be bottom, left)?
Any idea how to put the text_box over the whole screen AND MAKE IT INVISIBLE?
Do you know how to automatically select the text_box(so you write there)?

Thanks for any help you can offer!

[white_haired_uncle]

Why is my T.text_box in the screen center(tho it's defined to be bottom, left)?

I'm terrible at getting things to line up, but I did struggle with something similar recently. I could not get my text in a label to be left aligned. It turns out it was left aligned, but the column it was in was centered. Or maybe it was the column that that column was in. The point is I was just looking in the wrong place, even though it seemed so obvious to me that "it didn't work".

At some point I'm going to try to work up an example of this, probably using colored borders to show where each column/cell/widget is placed.

Any idea how to put the text_box over the whole screen AND MAKE IT INVISIBLE?

I only know how to make a dialog invisible. But I wonder if you could use a stacked_widget (or canvas?) to place an image (blank.png) over the top of it.

Do you know how to automatically select the text_box(so you write there)?

There's wesnoth.set_dialog_focus and gui.widget.focus that probably do that. Never used them.

[white_haired_uncle]

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).

Those don't exist. All core widgets are handled in C++.

Okay. Another idea I had was that somewhere in the source there must a "mapping" of properties to widgets (or their subclass(es)) for the Lua API. I don't care about the internals, but if I could find that I should be able to ascertain what I can do in the API.

[Celtic_Minstrel]

If you mean in documentation, that would be LuaAPI/types/widget. If you mean in the source code, the relevant file is lua_widget_attributes.cpp.

[white_haired_uncle]

If you mean in the source code, the relevant file is lua_widget_attributes.cpp.

That looks like the one. If I read that correctly, a stacked_widget has property selected_index:

Code: Select all

WIDGET_SETTER("value_compat,selected_index", int, gui2::stacked_widget)

as well as visible, because it is a child of styled_widget:

Code: Select all

WIDGET_SETTER("visible", lua_index_raw, gui2::styled_widget)

[Celtic_Minstrel]

Pretty much. Just be aware that that also includes deprecated things (which is mostly value_compat and callback).

[ZombieKnight]

There's wesnoth.set_dialog_focus and gui.widget.focus that probably do that. Never used them.

Where to put "gui.widget.focus(test_text)"?
(if test_text is the right parameter)
It doesn't work after gui.show_dialog, nor in dialog preshow... so idk what to do with that?

[ZombieKnight]

Thanks!
Oh dumb me, this works "dialog.test_text:focus()"

[ZombieKnight]

Thanks
I use

Code: Select all

dialog:set_canvas(1, { } )

To hide the label background...Any idea how to hide text_box background?
...
(optional so far ^^)And how to resize it?
...
How to close the dialog on the first >space< input?
How to erase the text from text_box, when any other character (>a<, >q<, >b<) is typed there?

[Ravana]

Compare the input value, and if it is ' ' then do one thing, else do other thing.

[white_haired_uncle]

Code: Select all

dialog.test_text.on_modified=function()
   if dialog.test_text.text == " " then dialog:close() end
   dialog.test_text.text =""
end

or something close
