Behaviorally: This change makes it so that Enter will never cancel
a dialog, unless that dialog only contains info to be read. Escape
will never unpredictably be treated as Enter. And some dialogs without
Escape to cancel, now can be canceled with Escape.
A lot of this just refactors dialogs to define the cancel button
at the top, not as a hotkey on a cancel button deep in the XML.
I think this makes enter/escape behavior in dialogxml files more
legible at a glance.
I'm planning to make it so the Enter key will never cancel a yes/no dialog. To do this, I'm adding an Escape button to dialogs. So cancel/accept keyboard shortcuts will be predictable and intuitive. Dialogs that require extra confirmation will have a 'really confirm' LED.
Search field starts out hidden. When the button is
clicked, the field and other controls appear, and
the button takes over the enter key. Ctrl+Enter
clicks okay (so if search is not opened, either
Enter OR Ctrl+Enter will click okay)
The text in the various help dialogs that was previously baked into an image is now drawn as text, meaning that it benefits from text unblurring when scaling is active.
This entails some small changes to layout, since it's a different font.
Dialog engine changes:
* A new picture type allowing to draw the inventory button icons directly into a dialog.
* A new widget type that simply draws a line between two points.
The picker is used in the special node dialog and also in monster abilities.
Some changes were made to the game as well:
* If the rotatable wall is used for a field missile or touch ability, there's no longer an option for the designer to pick an orientation. Instead, it behaves like the rotatable wall in a radiate field ability, selecting an orientation based on the creature's facing direction.
* The magic values sent to place_spell_pattern for direct damage were rearranged to match the order of the eDamageType enum. This should have no effect, since the core place_spell_pattern function is only called by the various wrapper overloads. It also simplifies the code quite a bit.
* The Protective Circle spell pattern is now exposed to the place patten special nodes. It can be used as just a radius 4 circle, but the effect of different layers of fields can also be obtained by specifying a field type or damage type of -1.
There is also a change to the dialog engine:
* Calling setText() also implicitly calls recalcRect()
The limit of 3 saved item rectangles has been removed - you can now add as many as you want.
However, the 1 per town limit is now strictly enforced.
The saved item rectangle is now shown with a cyan border when editing town.
In effect, this is a combination of two of the previous pickers:
the location picker, and the editable string picker.
This required quite a significant rework of how the tilemap places its children.
Currently it's only used in special node editing.
I plan to add its use in many other places too though.
