-(re)set _rename_[id/what] to -1 to catch invalid calls (main_gui.c)
-Only invalidate widget of pause/ff instead of whole window (main_gui.c)
-Remove numbering from WE_ and WC_ as it's not needed, also remove
non-existing windowclasses (window.h, openttd.h)
-Give names to some of the enums (window.h)
-In UninitWindowSystem not only free malloc'd widgets, but also reset the z-array (window.c)
-Some coding style, comments, etc.
- using one engine list instead of 3
- removed engine filters (loco, wagons, helicopters, etc.)
- EngineList code isolated from GUI (moved to helpers.cpp - reusing CBlobT code which does exactly what is needed for EngineList)
- removed unnecessary "optimization" (rebuild and sort engine list on each WE_PAINT)
structs inside their array, and possibly invalidating pointers higher up.
Meaning that any function called within an wndproc could cause unknown/invalid pointers
once control was returned to this function. Solved by the introduction of an extra
abstraction layer, an array of z-window positions that is only concerned with the
pointers.
-Codechange: closing all windows for a player will now loop all windows and close those, which got the player as caption instead of having a list of windows to close
some special values (WDP_) instead of checking window-class. This also fixes FS#172
now that we can position windows arbitrarily and are not restricted to window-classes.
to allow clicking if a button was disabled. This has been superseded in r212 with
general code that doesn't allow any click events for disabled buttons.
WWT_IMGBTN must contain an image for drawing. Renamed WWT_PANEL_2 to WWT_IMGBTN_2
because that is what it is. Added WWT_PUSHBTN that is either just a pushable button,
or a textbutton, which text's drawn dynamically independent of widget.
The functions required to do so are to be found in window.h.
Rather then use the old deprecated disabled_state, hidden_state and click_state uint32 variables,
we now need to use accessors like SetWindowWidgetDisabledState, SetWindowWidgetHiddenState or SetWindowWidgetLoweredState.
This is the final commit for the merge of XTDwidget branch.
This gives the ability to invalidate some window data and recalculate as needed instead of doing it for each WE_PAINT
This event is called right away when using InvalidateWindowData(), so it may be a good idea to set a bool or similar in the window
or similar and then act on that bool in WE_PAINT instead of doing a lot of stuff in WE_INVALIDATE_DATA as it might be called more than once before WE_PAINT is called
InvalidateWindowData() will not automatically repaint the window, so if you want to repaint it as well, you need to mark it dirty as well.
Made the depot windows use WE_INVALIDATE_DATA to set when to generate the engine and wagon lists instead of at each redraw
It makes no sense to regenerate the list when say using the scrollbar if we know that no vehicle have entered or left the list
NOTE: currently there is a piece of code to generate the list when it's not needed and compare it to the stored list and assert if they mismatch
This check is somewhat slow and kills the whole idea of WE_INVALIDATE_DATA, so it's a short lived one to verify that InvalidateWindowData() is used everywhere where it's needed
Example: make a train transport iron ore from A to B, then it visits a depot and refits to steel
It then transport steel back to A or near A if there is a factory and then it visits another depot to refit to iron ore again
This is controlled in the orders. If a goto depot order is lightlighted, then "Unload" changes to "Refit"
Control click "Refit" removes the refit part of the order (as the tooltip says)
The player will still pay the normal refit costs
Known issues:
If a vehicle is not in a depot, then the refit window will fail to tell refitted cargo capacity
Refit costs in the refit window can sometimes print 0 when it should not because the refit calculation is unaware that the vehicle will be refitted in between
Warning: autoreplace got a protection against replacing something so you get a new cargo type, but it can fail here. In the iron ore/steel example, it can see that
the vehicle carries iron ore and the new one can be refitted to iron ore, then it will replace. It will not check to see that it's valid for steel as well.
This is something to look into in the future
This change is intended to make it easier to make depot behaviour consistent
and faster to code when adding more features in the future
The user interface should hopefully not be affected by this
This will ensure that you can always get the same list when checking for vehicles in a depot (no need to duplicate code for each place, that needs such a list)
Since the vehicles are only looped once for each redraw, drawing speed is around twice as fast (measured to be 114%-121% faster depending on the number of vehicles in the game)
