/*
* osxctrls.m: OS X implementation of the dialog.h interface.
*/
#import <Cocoa/Cocoa.h>
#include "putty.h"
#include "dialog.h"
#include "osxclass.h"
#include "tree234.h"
/*
* Still to be implemented:
*
* - file selectors (NSOpenPanel / NSSavePanel)
*
* - font selectors
* - colour selectors
* * both of these have a conceptual oddity in Cocoa that
* you're only supposed to have one per application. But I
* currently expect to be able to have multiple PuTTY config
* boxes on screen at once; what happens if you trigger the
* font selector in each one at the same time?
* * if it comes to that, the _font_ selector can probably be
* managed by other means: nobody is forcing me to implement
* a font selector using a `Change...' button. The portable
* dialog interface gives me the flexibility to do this how I
* want.
* * The colour selector interface, in its present form, is
* more interesting and _if_ a radical change of plan is
* required then it may stretch across the interface into the
* portable side.
* * Before I do anything rash I should start by looking at the
* Mac Classic port and see how it's done there, on the basis
* that Apple seem reasonably unlikely to have invented this
* crazy restriction specifically for OS X.
*
* - focus management
* * I tried using makeFirstResponder to give keyboard focus,
* but it appeared not to work. Try again, and work out how
* it should be done.
* * also look into tab order. Currently pressing Tab suggests
* that only edit boxes and list boxes can get the keyboard
* focus, and that buttons (in all their forms) are unable to
* be driven by the keyboard. Find out for sure.
*
* - dlg_error_msg
* * this may run into the usual aggro with modal dialog boxes.
*/
/*
* For Cocoa control layout, I need a two-stage process. In stage
* one, I allocate all the controls and measure their natural
* sizes, which allows me to compute the _minimum_ width and height
* of a given section of dialog. Then, in stage two, I lay out the
* dialog box as a whole, decide how much each section of the box
* needs to receive, and assign it its final size.
*/
/*
* As yet unsolved issues [FIXME]:
*
* - Sometimes the height returned from create_ctrls and the
* height returned from place_ctrls differ. Find out why. It may
* be harmless (e.g. results of NSTextView being odd), but I
* want to know.
*
* - NSTextViews are indented a bit. It'd be nice to put their
* left margin at the same place as everything else's.
*
* - I don't yet know whether we even _can_ support tab order or
* keyboard shortcuts. If we can't, then fair enough, we can't.
* But if we can, we should.
*
* - I would _really_ like to know of a better way to correct
* NSButton's stupid size estimates than by subclassing it and
* overriding sizeToFit with hard-wired sensible values!
*
* - Speaking of stupid size estimates, the amount by which I'm
* adjusting a titled NSBox (currently equal to the point size
* of its title font) looks as if it isn't _quite_ enough.
* Figure out what the real amount should be and use it.
*
* - I don't understand why there's always a scrollbar displayed
* in each list box. I thought I told it to autohide scrollers?
*
* - Why do I have to fudge list box heights by adding one? (Might
* it be to do with the missing header view?)
*/
/*
* Subclass of NSButton which corrects the fact that the normal
* one's sizeToFit method persistently returns 32 as its height,
* which is simply a lie. I have yet to work out a better
* alternative than hard-coding the real heights.
