Can GUI2 tags be used directly in WML?

[Pentarctagon]

Is it possible to directly call [grid]/[helptip]/[tooltip]/etc in WML? Or can they only be used via wesnoth.show_dialog()? The wiki says show_dialog() is equivalent to [resolution], but then using [resolution] gives an error about it not being supported.

Also, since the wiki documentation for the widgets is rather sparse, is there anything that is essentially a popup box that can be dismissed by a click anywhere on the screen?

I was looking for functions like this some time ago, but didnt found any. I think you cant make gui in wml. If none of developers will prove Im wrong, im going to write framework for this.

Not that I know of, but I was considering the possibility to create a WML tag with lua that would add this possibility. Showing it should be a trivial thing to do. However, the callbacks are quite easy to manage. Should I try to create something like that for you (maybe with a callback support inferior equal to the possibilities in lua)?

It's not a huge deal for me at least, since I can sort-of-mostly work around it like this:

Code: Select all

[set_variables]
  name="dialog_box"
  [value]
    
    [tooltip]
      id="tooltip_large"
    [/tooltip]
    [helptip]
      id="tooltip_large"
    [/helptip]
    [grid]
      [row]
        [column]
          [grid]
            
            [row]
              [column]
                horizontal_grow="true"
                [listbox]
                  id="help_list"
                  [list_definition]
                    [row]
                      [column]
                        horizontal_grow="true"
                        [toggle_panel]
                          [grid]
                            [row]
                              
                              [column]
                                horizontal_alignment="left"
                                [image]
                                  id="help_list_icon"
                                [/image]
                              [/column]
                              [column]
                                [label]
                                  id="help_list_label"
                                [/label]
                              [/column]
                              
                            [/row]
                          [/grid]
                        [/toggle_panel]
                      [/column]
                    [/row]
                  [/list_definition]
                [/listbox]
              [/column]
            [/row]
            
            [row]
              [column]
                [grid]
                  [row]
                    
                    [column]
                      [button]
                        id="ok"
                        label="OK"
                      [/button]
                    [/column]
                    [column]
                      [button]
                        id="cancel"
                        label="Cancel"
                      [/button]
                    [/column]
                    
                  [/row]
                [/grid]
              [/column]
            [/row]
            
          [/grid]
        [/column]
        
        [column]
          [image]
            id="the_image"
          [/image]
        [/column]
        
      [/row]
    [/grid]
    
  [/value]
[/set_variables]
[lua]
  code=<<
        local result = wesnoth.show_dialog(wesnoth.get_variable("dialog_box"), preshow, postshow)
  >>
[/lua]

but if there was a way to do it without a workaround, then obviously I'd rather do it that way. Honestly I'm more interested in the documentation, since right now the wiki on GUI2 tags is incomplete at best.

[Celtic_Minstrel]

There is currently no way to embed GUIWML inside ActionWML, unless of course you create a custom WML tag that invokes wesnoth.show_dialog.

The wiki says show_dialog() is equivalent to [resolution], but then using [resolution] gives an error about it not being supported.

The config passed to wesnoth.show_dialog is equivalent to the contents of a [resolution] tag. The [resolution] tag cannot be nested within itself, so naturally including one in the config passed to wesnoth.show_dialog would be an error.

Also, since the wiki documentation for the widgets is rather sparse, is there anything that is essentially a popup box that can be dismissed by a click anywhere on the screen?

If you're looking for a popup menu such as the resolution selector in preferences, that would be a [menu_button]. Since the wiki documentation for GUIWML hasn't been updated for awhile, it may still be listed there as [combo_box] instead, and if you were working in 1.12 you'd have to use that as well. For a popup with checkboxes, like addon types dropdown, it would be [multimenu_button], but there may be some problems with using those from Lua at the moment.
