so I don't forget:
|
|
- Window.SizeToFit() or WIndow.OptimalSize() (use: `Window.SetOptimalSize())`) for sizing a window to the control's interest
|
|
- Control.Show()/Control.Hide()
|
|
- Groupbox
|
|
- see if we really need to track errors on a lot of places that report errors
|
|
- it appears GTK+ and Cocoa both either don't provide a convenient way to grab errors or you're not supposed to; I assume you're supposed to just assume everything works... but on Windows we check errors for functions that return errors, and there's no guarantee that only certian errors will be returned...
|
|
- character-limited entry fields, numeric entry fields, multiline entry fields
|
|
- possible rename of LineEdit?
|
|
- especially for password fields - NewPasswordEntry()?
|
|
- [Mac OS X] Listbox should have a border style
|
|
- [Windows] a different border on LineEdits and Listboxes?
|
|
- padding and spacing in Stack
|
|
- allow Combobox to have initial settings
|
|
- Combobox and Listbox insertions and deletions should allow bulk (...string)
|
|
- Combobox/Listbox.DeleteAll
|
|
- Combobox/Listbox.Select (with Listbox.Select allowing bulk)
|
|
- Checkbox.Check or Checkbox.SetChecked
|
|
- Listbox.SelectAll
|
|
- should Labels be selectable?
|
|
- should message box text be selectable on all platforms or only on those that make it the default?
|
|
- Listbox/Combobox.Index(n)
|
|
- Index(n) is the name used by reflect.Value; use a different one?
|
|
- change sysData.make() so it does not take the initial window text as an argument and instead have the respective Control/Window.make() call sysData.setText() expressly; this would allow me to remove the "no such concept of text" checks from the GTK+ and Mac OS X backends
|
|
- Message boxes should not show secondary text if none is specified.
|
|
- note that you can change event channels before opening the window; this allows unifying menus/toolbars/etc.
|
|
- will probably want to bring back Event() for this (but as NewEvent())
|
|
- add bounds checking to Area's sizing methods
|
|
- describe thread-safety of Area.SetSize()
|
|
|
|
important things:
|
|
- because the main event loop is not called if initialization fails, it is presently impossible for MsgBoxError() to work if UI initialization fails; this basically means we cannot allow initializiation to fail on Mac OS X if we want to be able to report UI init failures to the user with one (which would be desirable, maybe (would violate Windows HIG?))
|
|
- figure out where to auto-place windows in Cocoa (also window coordinates are still not flipped properly so (0,0) on screen is the bottom-left)
|
|
- also provide a method to center windows; Cocoa provides one for us but
|
|
- I think Cocoa NSButton text is not vertically aligned properly...?
|
|
- and listbox item text is too low?
|
|
- NSPopUpButton does allow no initial selection ([b setSelectedIndex:-1]); use it
|
|
- need to use it /after/ adding initial items, otherwise it won't work
|
|
- find out if I can do the same with the ListBoxes
|
|
- NSComboBox scans the entered text to see if it matches one of the items and returns the index of that item if it does; find out how to suppress this so that it returns -1 unless the item was chosen from the list (like the other platforms)
|
|
- some Cocoa controls don't seem to resize correctly: Buttons have space around the edges and don't satisfy stretchiness
|
|
- there's no GTK+ or Cocoa error handling whatsoever; we need to figure out how it works
|
|
- I know how Cocoa error handling works: it uses Cocoa exceptions; need to figure out how to catch and handle them somehow
|
|
- make sure GTK+ documentation version point differences (x in 4.3.x) don't matter
|
|
- button sizes and LineEdit sizes on Windows seem too big; Comboboxes have margins
|
|
- Cocoa has similar margining issues (like on Comboboxes)
|
|
- sometimes the size of the drop-down part of a Combobox becomes 0 or 1 or some other impossibly small value on Windows
|
|
- make gcc (Unix)/clang (Mac OS X) pedantic about warnings/errors; also -Werror
|
|
- make sure scrollbars in Listbox work identically on all platforms (specifically the existence and autohiding of both horizontal and vertical scrollbars)
|
|
- pin down this behavior; also note non-editability
|
|
- the size of Listboxes on Windows does not fill the requested space completely (wait, wasn't there a style that governed this?)
|
|
- make sure mouse events don't trigger if the control size is larger than the Area size and the mouse event happens outside the Area range on all platforms
|
|
|
|
super ultra important things:
|
|
- the windows build appears to be unstable:
|
|
- 64-bit crashes in malloc in wine with heap corruption warnings aplenty during DLL loading; in windows 7 it works fine
|
|
- 32-bit: it works, but if I save the class name converted to UTF-16 beforehand, wine indicates that the class name is replaced with the window title, so something there is wrong...
|
|
- handle in-library panics (internal errors) by reporting them to the user
|
|
- david wendt is telling me he's getting frequent crashes on his end with the GTK+ amd64 build...
|
|
TODO re-evaluate; I think I fixed them all ages ago now
|
|
- occasionally I get
|
|
panic: error sending message to message loop to call function: Invalid thread ID.
|
|
when starting up the windows/386 build; race in ui()/msgloop()?
|
|
- happens the first time I run a new build in wine; also if my computer is running too slowly when running in wine
|
|
- GTK+: stderr is flooded with
|
|
```
|
|
(test:17575): Gdk-CRITICAL **: gdk_device_ungrab: assertion 'GDK_IS_DEVICE (device)' failed
|
|
|
|
(test:17575): Gtk-CRITICAL **: gtk_device_grab_remove: assertion 'GDK_IS_DEVICE (device)' failed
|
|
```
|
|
figure out why
|
|
- I think it has to do with invalid list deletions; roll back the panics and check
|
|
- the user can still [NSApp terminate:] from the Dock icon, bypassing Go itself
|
|
- ideally we need a QuitItem() function for this case if/when we add menus
|
|
- Cocoa: NSScrollView support is hacky at best
|
|
- https://developer.apple.com/library/mac/documentation/cocoa/Conceptual/NSScrollViewGuide/Articles/Creating.html#//apple_ref/doc/uid/TP40003226-SW4 the warning about pixel alignment may or may not be heeded, not sure
|
|
- frame sizes are a bit of a hack: the preferred size of a NSScrollView is the preferred size of its document view; the frameSize method described on the above link might be better but a real solution is optimal
|
|
- make sure the image drawn on an Area looks correct on all platforms (is not cropped incorrectly or blurred)
|
|
- when resizing a GTK+ window smaller than a certain size, the controls inside will start clipping in bizarre ways (progress bars/entry lines will just cut off; editable comboboxes will stretch slightly longer than noneditable ones; the horizontal scrollbar in Area will disappear smoothly; etc.)
|
|
- the window background of a GTK+ window seems to be... off - I think it has to do with the GtkLayout
|
|
- see update 18 March 2014 in README
|
|
- resizing seems to be completely and totally broken in the Wayland backend
|
|
- scrolling Areas in wine by clicking in the page scroll area often causes the main thread to lock up; uitask does not
|
|
- make sure the first and last rows and columns of an Area are being drawn on Windows
|
|
- clicking on Areas in GTK+ don't bring keyboard focus to them?
|
|
|
|
important things:
|
|
- make specific wording in documentation consistent (make/create, etc.)
|
|
- document minor details like wha thappens on specific events so that they are guaranteed to work the same on all platforms (are there any left?)
|
|
- what happens when the user clicks and drags on a listbox
|
|
- should field descriptions in method comments include the receiver name? (for instance e.Held vs. Held) - see what Go's own documentation does
|
|
- make passing of parameters and type conversions of parameters to uitask on Windows consistent: explicit _WPARAM(xxx)/_LPARAM(xxx)/uintptr(xxx), for example
|
|
- do this for type signatures in exported functions: (err error) or just error?
|
|
- do this for the names of GTK+ helper functions (gtkXXX or gXXX)
|
|
- on windows 7, progress bars seem to animate from 0 -> pos when you turn off marquee mode and set pos; see if that's documented or if I'm doing something wrong
|
|
- clean up windows struct field names (holdover from when the intent was to make a wrapper lib first and then use it rather than using the windows API directly)
|
|
- make all widths and heights parameters in constructors in the same place (or drop the ones in Window entirely?)
|
|
|
|
far off:
|
|
- localization
|
|
- strip unused constants from the Windows files
|
|
- combine more Windows files; rename some?
|
|
- tab stops
|
|
|
|
maybe:
|
|
- rename Stack to Box?
|
|
- make Combobox and Listbox satisfy sort.Interface?
|
|
- should a noneditable Combobox be allowed to return to unselected mode by the user?
