Double checked BeOS R5 & Haiku R1/A4 and BTextView should be 356
bytes, somewhere since then we've added 4 bytes. So, this commit
reduces the class size from 360 back to 356 by removing 1 reserved
int32 (instead of 2).
I believe the class size changed in hrev46798 as a result of adding
2 bools (1 byte each padded out to 4 bytes).
Sorry for the noise.
In hrev46796 I added two new private methods: _PreviousLineStart(),
and _NextLineEnd() which increased the size of the class breaking
binary compatability because I forgot to decrement the reserved array.
This commit decrements the reserved array restoring the class size
to the original size fixing the binary compat issue.
Thanks Axel for noticing.
The order is updated so the virtual methods appear in the same order
that they did in BeOS R5 with methods new to Haiku added to the bottom.
Perform() moves up, all other methods move below GetDragParameters(),
the last virtual method in BeOS R5's TextView.h.
Make Cmd+Left and Cmd+Right work the same as Option+Left and
Option+Right, that is, they do word-wise navigation.
Make Option+Up go to beginning of paragraph and Option+Down go to end
of paragraph like Cmd+Left and Cmd+Right used to.
Unfortunately option shortcuts are currently eaten by S&T until #9431
gets fixed.
* Command+Left goes to beginning of line, ignoring softwrap
* Command+Right goes to the end of line, ignoring softwrap
* Home goes to beginning of line, accounting for softwrap
* End goes to end of line, accounting for softwrap
* Option+Left goes to previous word
* Option+Right goes to next word
* Command+Home and Command+Up go to beginning of document
* Command+End and Command+Down go to end of document
Shift with any of the above also selects the text.
This is similar to how the text editor Eddie works.
* Make pointer style consistent, const char* name instead of const char *name.
* Lots of parameter renaming.
* in parameters don't get anything special, just font, or length instead of
inFont, inLength.
* out parameters get a leading _ so *outWidth becomes *_width for example.
* We don't detail private function in the Haiku book and this class has a bunch
so keep the documentation in the file but use regular comments instead.
* Normalize the parameter names between cpp file and header.
* Some minor whitespace fixes.
No functional change intended.
* Adjust BTextView to use B_COMMAND_KEY instead of B_CONTROL_KEY
for wordwise navigation and jumping to the top and bottom.
This requires a shortcut, which is only installed if there is
none already (for the groups B_LEFT_ARROW/B_RIGHT_ARROW and
B_HOME/B_END). As a result, wordwise navigation no longer works
in Mail, for instance.
Fixed the usual issues - printf format strings, uint32 instead of
addr_t, etc. One thing that isn't so nice is several places where
BList is used to store (u)int32, these require a double cast to addr_t
then void* to silence a warning on x86_64.
This fixes#7022 and is mostly based on the patch attached to that ticket, with
these changes:
- The patch was adding this to the private _TextInput_ class, not BTextView.
- The patch had a Clear menu item too. I removed that due to the different
semantics between Clear in a BTextView and in a TextInput. The former just
clears the selection where the latter clears the whole view.
We could later add a virtual callback for adding menu items to this context
menu which could be used to add Clear with the two semantics in each class
(this is mainly needed for the enabling logic...each class could handle a clear
message in its own way.) This callback could also obviously be used for other
things, like a spell-check menu or whatever an application would want to add.
Since BTextView has 10 free virtual slots it seems reasonable to add.

during the width calculation
* used _TabExpandedStyledWidth() at all places that need to expand tabs,
fixing #4822
* removed _StyledWidthUTF8Safe() as it didn't make sense - we now perform
the same auto-scrolling horizontally as we do vertically

* switching from wrapping to non-wrapping mode triggers a recomputation of
the text rect
* non-wrapping mode now triggers updating of the data rect for the horizontal
scrollbar as needed, fixing #4705
* corrected a couple of width computations that confused bounds and text
rect width, leading to drawing artefacts at the end of a line
* unified computation of text rect width to always take all lines into
account (not just the first one)
* some cleanup

although it should have been safe before, too, since BTextView neither
has inline methods nor any friends that live outside of libbe
* added new member fLastClickOffset in order to be able to restore the
triple-click handling (linewise selection)
* renamed fClickOffset to fCaretOffset, as that is what it really is
now

* non-editable textviews no longer draw the caret
* the cursor keys scroll immediately, not only when the (invisible) caret
reaches the views bounds
* HOME/END work more reliably
* any selection stays active throughout keyboard navigation
Tested with AboutSystem, Mail, StyledEdit and Beam - seems to work ok

in order to maintain the null-style appropriately, if required
* finally fix#3040 for real (a single style is now maintained at all times
for non-stylable textviews)
* the caret is now being drawn with the correct size, even if it is on
the empty line at the end of the buffer and a specific font size has been
requested

more work concerning navigation within BTextView:
* pressing HOME on last line works again
* made public versions of LineAt() do what is required to pass back the
correct value even for the last line of the buffer (original implementation
has been moved to private _LineAt())
* PAGE_UP/PAGE_DOWN now moves the view by the bounds-height, making the
behaviour somewhat less confusing (IMHO, please shout if that's not
acceptable for you)
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30459 a95241bf-73f2-0310-859d-f6bbb57e9c96
* renamed _FindXXXWordBoundary() methods to _Previous/_NextWordBoundary()
since the respective per-char methods are named this way
* started to work on improving the behaviour of page-up/page-down
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30012 a95241bf-73f2-0310-859d-f6bbb57e9c96
* reverted my recent change that caused Mail to always show the end
of mails 8-) and now invoke ScrollToOffset() wherever it was missing
(mostly in keyboard-related methods)
* _DoInsertText() only moves the caret if the text has been inserted
in front of the caret, not after it
* overhauled selection by char/word/line and their extension mechanism
(which now behaves as the haiku shell)
* use strnlen() instead of strlen() in those versions of Insert() which
accept a length parameter, as strlen can potentially waste a lot of
cycles skipping the whole string, when all we want is to clamp the length.
* cleanup (some of it automatic removal of trailing whitespace)

we request the drawing via Invalidate() - this make use of the app-server's
potential double buffering, whenever that is active. This change reduces
flickering in VESA mode considerably.

gWidthBuffer.
* Tracker PoseView now uses BPrivate::gWidthBuffer instead of it's own
instance.
* TextView.h and PoseView.h are now a little cleaner.
* InterfaceDefs.cpp now deletes gWidthBuffer in _fini_interface_kit_().
* Added binary compatibility support for NetPositive in WidthBuffer.h and .cpp.
Obviously it kind of defeats the purpose of having WidthBuffer neatly tucked
away in the BPrivate namespace, but Haiku should run NetPositive, I guess.
Fixes#2879.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28532 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added a layout friendly constructor - it's not so nice to use, though, since
the original one already doesn't get a BRect (we just don't need the
resizing mode, and have to set the B_SUPPORTS_LAYOUT flag).
* Refactored size/frame computation a bit.
* Cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28258 a95241bf-73f2-0310-859d-f6bbb57e9c96
* The class calculates a minimum width now, which is based on the line height,
this may also fix the bug with the small text inputs in the Pe Find window.
* Added TODOs about implementing GetHeightForWidth(), which may be a good idea
when a BTextView is used as non-editable informative text in an interface,
and one wants to make sure that the entire text is shown.
* Replaced the call to _Refresh() in Draw(), which recalculates all the line
breaks for no reason with _DrawLines() again. The TODO mentioned that text
will be drawn without drawing the background first, but maybe this is a
relict from times where Draw() was invoked directly? At least I cannot see
any negative consequences, and this should be much more efficient.
(Other than that, this patch should hopefully have no potential negative
side effects...<crosses fingers>)

BTextView classes:
* Declared the directly used BTextView helper classes as private BTextView
classes and changed all affected files.
* Realized that Tracker's BPoseView was (accidentally?) using what used to
be _BWidthBuffer_. It had declared it's own class with the same name and
same members/size in headers/private/tracker/TextViewSupport.h, but the
implementation was nowhere to be found. I can only explain this that
the BTextView implementation was then actually linked and used. But the big
problem was that it was used without locking (unlike in BTextView)! When
many Tracker windows opened during system startup or later and they happened
to each request characters not yet in the cache, I imagine things could have
gone bad and corrupted memory. Anyways, since I can see the usefulness of
the cache, BPoseView uses BTextView::WidthBuffer on purpose now. And I moved
the locking inside BTextView::WidthBuffer::StringWidth().
* Adjusted InterfaceDefs.cpp accordingly.
* TODO: Move subsequent classes into BTextView namespace as well, ie derived
classes that BTextView doesn't directly know about. All stuff in src/kits/
inteface/textview_support/
* Added preliminary and not yet implemented layout friendly BTextView
constructors.
* I will try to handle the insets imposed by BTextView::fTextRect a bit
differently when used inside the new layout management framework. For this,
I added BTextView::SetInsets() and GetInsets(). SetInsets() doesn't do
anything yet.
So far, everything seems to work still... ;-)

* Renaming things in Tracker list mode no longer magically grows the text view.
* ScrollToOffset() is not supposed to depend on the existence of any scroll
bars, in R5 text views simply scroll to where they need to. This fixes
renaming things in Tracker when hitting the window bounds (text widget stops
growing and starts to autoscroll) and also the Text tool in WonderBrush.
* _ScrollToOffset() is therefor no longer needed.
* The insets of the text rect are not so interesting as the original width.
In auto resizing mode, the original width is important when there is no
container view. In this setup, the text rect auto resizing is mainly needed
for auto scrolling, but it should never shrink below the original size.
* Further improved auto scrolling for right aligned and center aligned text
views, it works like R5 now. Also take the line height into account when
checking for the bounds bottom. Removed extra spacing for vertical
scrolling.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24130 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Placed _BTextInput_ into BPrivate namespace.
* Made _BTextInput_::AlignTextRect() smarter, it centers the line vertically,
for the case that the BTextControl has a larger label font. Improved insets
for asthetics.
* Used _BTextInput_::AlignTextRect() consistently in BTextControl, no more
custom calls to SetTextRect(). Account for minimum vertical inset of 2
pixels in GetPreferredSize().
* Consistendly select all text when gaining focus in _BTextInput_.
* Override MouseDown() in case the control did not have focus before, or else
BTextView::MouseDown() will deselct the text again and place the cursor.
(in line with BeOS behavior)
* Removed unused fBool member from _BTextInput_ and other cleanup.
BTextView:
* Reimplemented BTextView::_AutoResize() so that it works well with
BTextControl and autoscrolling when the alignment is not B_ALIGN_LEFT.
I needed two new members for this, fLeftInset and fRightInset which are
the original insets from the fTextRects. It might currently be broken
for renaming things in Tracker, I will have to check. _AutoResize() no
longer messes up the fTextRect insets.
* Fixed stray carrets sometimes being left over, mostly when auto scrolling,
but I observed them in other cases as well.
* Prevent negative scrolling offsets when autoscrolling. Fixes weird scrolling
offsets when navigating to the left.
* Reset scrolling to B_ORIGIN when SetText() is called. Fixes for example
starting to type in the middle of the control in Vision when entering new
text and autoscrolling was triggered before.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24101 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Rewrote TextView.h
* Renamed all private methods to have the underscore prefix.
And also:
* Whitespace and line width cleanup.

hence CancelInputMethod()), but it implements part of it. To avoid code
duplication, I added a private _SetRunArray() call, which does most of
the work, except cancelling the input method, and calling Refresh().
Removed some unneeded code from CancelInputMethod(), some small changes
in HandleInputMethodChanged.
