I get these compiler warnings a couple of times.

Some comments regarding the UI.

I think we should keep the UI consistent. Instead of checkboxes please use the icons/buttons that are used in the building's window. The same applies for the priority settings. We use traffic lights instead of buttons.

[Benedikt Straub (nordfriese)]

Fixed the compiler warnings and made the UI design consistent. I did not convert the Stop and Launch Expedition to toggle-buttons though because it is never clear with such buttons whether the icon shows the current state or the action taken by clicking it IMHO.

By the way, when clicking the Enhance button, the window will annoyingly switch to the first tab – this is unrelated to this branch, see bug 1818857.

[Toni Förster (stonerl)]

hmm. I would prefer icons but you are completely right. I opened a topic in the forum:

Your buttons are a little too big. The buttons for in-/decreasing the wares are 24x24 while yours are 25x30.

Also, some wares are covered by the button; see the fish in the tavern (I guess that is because of your buttons being to big)

[Toni Förster (stonerl)]

With this branch I get crashes after a while. Not sure if the culprit is this branch or something in trunk, though.

[Benedikt Straub (nordfriese)]

Took care of the warnings and fixed the input queue layout.

A backtrace would be helpful…
Did you get this while an (enhanced?) constructionsite was being built, or when a constructionsite was being completed? I got similar crashes before, but I thought I had caught all corner cases now…

Assert fail fixed :)

[kaputtnik (franku)]

Looks like this branch breaks savegame compatibility. When trying to load a game which runs fine in trunk i get:

And another assertion.

[Benedikt Straub (nordfriese)]

This seems to be the same issue as the crash with animation ID -432781024, but with a more usable file&line number. Will push a fix soonish

[Benedikt Straub (nordfriese)]

Since the bug is not reproducible, I can´t be certain, but it should most likely be gone now

[Toni Förster (stonerl)]

Seems to be fixed.

[kaputtnik (franku)]

Trying to load a savgame from trunk prints now in a window (and console):

Game data error
buildingdata: building 524547: not found

Loading in trunk works fine. Save game: https://bugs.launchpad.net/widelands/+bug/1597310/+attachment/5264357/+files/construction_site_settings.wgf

[GunChleoc (gunchleoc)]

I am getting a similar error when loading our homepage reference screenshot savegame Build, so we already have a change to saveloading in trunk where we overlooked having to increase the packet number.

[Toni Förster (stonerl)]

Would it be possible to move the tabs for Warehouses' and Ports' to the top, instead of having to tab rows?

[Benedikt Straub (nordfriese)]

OK, will change it like this

[GunChleoc (gunchleoc)]

It would be nice if the tab was remembered after using the "enhance" button.

The target of the help button does not get updated when enhancing, e.g. construction site for deeper coal mine will show the coal mine instead.

"Launch expedition" should be "Start an expedition" like on the button for the finished port.

It would be nice if the extra options like "Start an expedition" or "Stop" would have the same UI buttons as the finished sites. I can live with the checkboxes though.

Should all be fixed now

> It would be nice if the tab was remembered after using the "enhance" button.

This is exactly the same as bug 1818857 so it should be fixed independent from this branch. There will likely be one catch-all fix for both flavours of the bug.

> It would be nice if the extra options like "Start an expedition" or "Stop" would have the same UI buttons as the finished sites. I can live with the checkboxes though.

What I could do is to render the appropriate icon next to the checkbox if you like. But unless we change the other UI elements in such a way that they show clearly what the current state is, there is no alternative to the checkboxes IMHO, since the current icons are only acceptable because one can see the active state elsewhere (stats string / expedition tab), which can not happen here.

[GunChleoc (gunchleoc)]

OK, let's leave the design as it is :)

This doesn't compile:

ow.cc.o -c ../src/wui/dismantlesitewindow.cc
In file included from ../src/wui/dismantlesitewindow.h:25:0,
                 from ../src/wui/dismantlesitewindow.cc:20:
../src/wui/buildingwindow.h: In member function ‘void BuildingWindow::set_building_descr_for_help(const Widelands::BuildingDescr&)’:
../src/wui/buildingwindow.h:99:30: error: ‘void Widelands::BuildingDescr::operator=(const Widelands::BuildingDescr&)’ is private within this context
   building_descr_for_help_ = d;
                              ^

Once that has been fixed, we still need to look at the code.

Refusing to merge, since Travis is not green. Use @bunnybot merge force for merging anyways.
