[GUI] various questions on lining stuff up
At this point, I simply detest trying to get anything to line up nicely in a gui. After countless hours of error and trial, I've come no closer to having even a theory about how this stuff works.
I have two lists of units. In the right column, a header and a list of units on the recall list. It's a treeview, because that's the only thing I was able to use for which I could find a way to get the names to line up neatly all left aligned. In the left column, I have a header, a (treeview) list of units that will be automatically recalled at the start of a scenario, and a multi_page that will hold either a spacer (big blank spot when nothing is selected) or a unit_preview_pane displaying the selected unit.
Issue #1. How do I force the headers (yellow text) to line up vertically? I've had a tiny bit of success with linked_groups getting things to line up horizontally, but that's mostly luck at this point. The "header_label" linked groups are my failed attempt.
Issue #2. When I select a unit, the unit_preview_pane sizes itself based on some rules I haven't figured out. Might be something like "if you can fit everything you have on the screen without using a scrollbar, but leaving at least ONE visible unit listed in the treeview above, take as much space as you need. What I'd really like to say is "treeview, your height is X, mp your height is Y. Always. Deal with it." (My gut says I'd prefer height in %, I'd settle for pixels). I don't want anything re-sizing itself, I want to define the layout.
I'll select item 12 from the list on the left for example. Not at all what I want.
Issue #3. I've selected item 12 on the list on the left, but you can't see that above. The list got scrunched and a scrollbar added, but the focus is not on the selected entry. Can I force this? I really do want to see which I have selected.
Also, those up and down buttons move selected units up or down on the left list (unit stays selected, but its position in list moves). If the selected unit moves to a place where it can't be seen without moving the scrollbar, the focus doesn't go with it and the bar doesn't move automatically.
I suspect this issue might have something to do with the fact that I'm using a treeview and sort of forcing it to act like a listbox. I'm not against using a listbox, that's what I started with, but I couldn't get the names to line up (I think I might be able to now based on something similar I'm also working on).
I'll apologize for the code now. It's a WIP, I barely know what I'm doing, and I'm still trying to develop a style which is readable but saves real estate. I wish I could cut out all the non-relevant stuff, but I'd probably mess something up so here it is warts and all.
Just in case anyone should care to try it to see what I'm struggling with, I've attached a saved game and my changes to the addon (https://github.com/Dugy/Legend_of_the_Invincibles). Menu item "Configure Autorecall (New)"

- The beginning, nothing selected.

- Take all the space you need there partner.

Re: [GUI] various questions on lining stuff up
I fixed issue #1 by setting vertical_alignment="top" on the column that contains the grid that contains the left "half" of the dialog.
Code: Select all
local dialogDefinition = {
T.tooltip { id = "tooltip" },
T.helptip { id = "tooltip_large" },
T.linked_group { id = "ar_position", fixed_width = true, },
T.linked_group { id = "ar_unit", fixed_width = true },
T.linked_group { id = "av_unit", fixed_width = true },
T.linked_group { id = "header_label", fixed_width = true },
T.grid {
T.row {
T.column {
T.grid {
T.row {
T.column { id = 'autorecall_list',
vertical_alignment="top",
T.grid {
T.row {
T.column {
T.label {
use_markup=true,
label = "<span size='large' color='yellow'>"
.. _"Units to be Automatically Recalled (" ..
#ar_list .. "/" ..
max_autorecall .. ")</span>" }
}
},
T.row {
T.column { autorecall_treeview }
},
}
},

Re: [GUI] various questions on lining stuff up
For item 2, you can use a stacked_widget with an invisible image layer set to the minimum size you want to reserve, then put your widget on top of that. Or look at the size_lock widget.
