While improving Android IME support (da38c1ed), text editor destructors
were updated to explicitly pass keyboard focus elsewhere.
As far as I remember, the change was intended to prevent the text input
system from trying to send input events to components while they were
being destroyed, in which case the TextInputTarget and Component bases
may be 'valid', but the data members referenced by the TextInputTarget
implementation may have been destroyed.
The motivation for removing these lines is that giving away focus and
sending a focus event can cause all components to become unfocused. This
is problematic in the case of slider text editors - pressing 'enter'
will cause the TextEditor to be destroyed, but the parent component will
fail to gain focus, so pressing 'tab' will not have any effect.
- Created a new detail namespace
- Moved shared module implementation details into the detail namespace
- Split dependencies so source files only rely on details in the detail namespace
- Removed all code from the juce_gui_basics.cpp file
A regression was introduced in d564e4931. Before that commit you
could use key up to jump into position zero of a multiline TextEditor
if the cursor was somewhere in the first line. Since that commit the
keypress had no effect. This change restores the earlier behaviour.
This commit fixes an issue when using large lineSpacing, where the caret
would jump to the end of the previous line when clicking between lines.
With the new behaviour the line spacing is considered to belong to the
previous line.
The commit also changes the behaviour observed when clicking in the
empty space before the first line. Until now the caret would jump into
the first character position. Now it behaves as if the space before the
first line would belong to the first line.
- Fixes an off-by-one error when navigating by rows, caused by treating
the table header as a row. The table header now has the header
accessibility role.
- Fixes a bug where reordering table columns would cause the table to
become inaccessible.
- Fixes a bug where the screen reader would try to navigate hidden table
columns.
- Fixes an issue where moving the VoiceOver cursor to a partially hidden
cell would cause the focus to move to the table itself, rather than to
the cell.
The TextHolderComponent and Viewport::componentHolder don't have any
accessible semantics, so they shouldn't be included in the accessible
component hierarchy.
Previously, when navigating in a text editor by words, the cursor would
get 'stuck' after moving a single word. This issue should now be
resolved.
Additionally, the cursor position was not updated properly when
adjusting a selection, and would instead be moved to the end of the
selected range. With this patch applied, the cursor should now be set to
the correct position when modifying selections. When extending a
selection backwards, the cursor will display at the beginning of the
selected range, rather than the end.
Finally, most Android apps announce the 'skipped' characters or words
whenever the cursor is moved, but this feature was broken in JUCE. This
patch enables this feature.
Previously, individual components had to ask the peer to hide and show
the keyboard, by calling textInputRequired() and
dismissPendingTextInput() respectively. When an onscreen keyboard (OSK)
was required, most Peer implementation would directly hide/show the OSK
inside these function. However, the iOS ComponentPeer implementation
instead listened to the application's global keyboard focus, and only
opened the OSK when the focused component was also a TextInputTarget
with active input.
The iOS scheme seems like a better design, as it enforces that the OSK
hiding and showing is synced with the keyboard focus of the application.
In the other implementations, it was possible for a Component to call
textInputRequired even when it didn't have the keyboard focus, putting
the application into an inconsistent state. The iOS scheme also makes
the TextInputTarget interface more useful, as it enforces that the OSK
will only display for components that implement TextInputTarget, and
return true from isTextInputActive().
This patch changes all Peer implementations to match the iOS
implementation, improving consistency. Each time the global keyboard
focus changes, refreshTextInputTarget is called automatically, and the
OSK is shown if the focused component is a TextInputTarget that returns
true from isTextInputActive, and hidden otherwise. Components can also
call refreshTextInputTarget manually. This should be done whenever the
component updates the return value of isTextInputActive(). Effectively,
the Peer is now responsible for keeping track of the focused
TextInputTarget, rather than allowing individual components to hide and
show the OSK at will.
Additionally, this patch adds an option to the TextEditor to
automatically dismiss the OSK when the mouse is clicked outside of the
editor. This should improve user experience on mobile platforms, where
touches on sibling components may cause a TextEditor to gain keyboard
focus and unnecessarily display the OSK.
