2021-05-20Add LevelIsHeader and LevelIsWhitespace as fold levels will become enum classNeil5-37/+45
later so not work well with '&'.
2021-05-19Bug [#2253]. Remove SC_ELEMENT_CARET_SECONDARY as it caused unexpected change toNeil2-5/+1
caret appearance for empty selection as empty selections can not be primary.
2021-05-16Include modifiers in SCN_INDICATORRELEASE notification.Damiano Lombardi1-1/+1
2021-05-15Protect against out-of-bounds layout cache level and remove unnecessary code.Neil2-3/+4
Make documentation more accurate.
2021-05-15Bug [#2253]. For SCI_SETSELALPHA, also update the alpha of secondary and ↵Neil Hodgson1-2/+5
no-focus states to avoid hiding text under opaque selections. This leads to very faint selections but that is preferrable to not being able to see text.
2021-05-14Do not set alpha of SC_ELEMENT_CARET_LINE_BACK unless already has a colour.Neil1-1/+3
2021-05-14Implement SC_LAYER_UNDER_TEXT so that selections, caret lines, and content areaNeil2-16/+24
markers can be drawn translucently under text.
2021-05-14Add elements for hot spots SC_ELEMENT_HOT_SPOT_ACTIVE andNeil4-22/+17
SC_ELEMENT_HOT_SPOT_ACTIVE_BACK.
2021-05-14Add SC_ELEMENT_WHITE_SPACE_BACK to set the background colour of visibleNeil4-16/+15
whitespace.
2021-05-14Feature [feature-requests:#1402] Add SC_ELEMENT_WHITE_SPACE to set the colour ofYX Hao4-22/+31
visible whitespace including translucency.
2021-05-14Draw EOL annotation shapes under text.Neil1-1/+1
2021-05-14Add method to mix colours in a proportion.Neil1-0/+11
2021-05-14Add SCI_MARKERSETLAYER to define layer on which to draw content area markers.Neil6-19/+42
This replaces the use of SC_ALPHA_NOALPHA for markers.
2021-05-12Switch caret line background colour to SC_ELEMENT_CARET_LINE_BACK element andNeil5-53/+81
add SetCaretLineLayer. Older caret line APIs SCI_SETCARETLINEVISIBLE, SCI_SETCARETLINEBACK, SCI_SETCARETLINEBACKALPHA now discouraged.
2021-05-11When setting or resetting elements, redraw if caused change.Neil3-13/+25
2021-05-11Implement SCI_GETELEMENTBASECOLOUR to return the default values for elementNeil1-0/+3
colours.
2021-05-11Add tests for element APIs. Fix SCI_GETELEMENTCOLOUR to return value includingNeil3-1/+21
alpha. Set selection and caret elements as allowing translucency.
2021-05-10Change the way that selections and carets are drawn to use the element APIs.Neil4-166/+195
2021-05-10Add elementBaseColours to hold default or system derived colours.Neil4-1/+42
Editor::UpdateBaseElements can be overridden by platform layers to set base colours although they should also do this when they detect changes in system settings.
2021-05-07Use shared_ptr for LineLayoutCache as it simpifies lifetime management.Neil5-91/+41
AutoLineLayout and other code no longer needed so removed.
2021-05-07Overallocate line layout cache so that don't reallocate too often.Neil1-2/+13
2021-05-07When resizing for Cache::page, move cached entries to correct positions.Neil2-21/+58
Hoist position calculation into EntryForLine method.
2021-05-07Add lineNumber_ argument to LineLayout constructor so always knows which line itNeil5-28/+35
is for. Add accessor for line number and method to say whether compatible with a line number and number of characters. Since LineLayout can report its line number, remove line argument from EditView::LayoutLine which simplifies calling it.
2021-05-07Ensure a line is only ever in one line layout cache entry. Preserve calculatedNeil1-29/+49
data where possible when overwriting a cache entry.
2021-05-08Feature [feature-requests:1373]. Make idle actions smoother by measuringNeil4-20/+25
per-byte and allowing just one line to be processed in a time slice. Very long lines will not distort estimation or block interaction as much.
2021-05-08Feature [feature-requests:1373]. Add methods for refining idle task durations.Zufu Liu2-0/+20
2021-05-05Remove deprecated AddCharUTF method.Neil2-8/+0
2021-05-05Avoid some warnings in ResetLineEnds.Neil1-3/+3
2021-05-05Hoist selection text colour into SelectionForeground function and whetherNeil3-32/+47
there is a selection text colour into ViewStyle::SelectionTextDrawn. Pass EditModel to SelectionBackground so focus can be used in a future change. Simplify code, use const and better names. Prefer explicit iterator type to auto in cases where it makes little difference.
2021-05-05Redraw when focus changes. Move hasFocus to EditModel where it can be used forNeil4-2/+6
drawing more easily.
2021-05-04Mark WidthF const noexcept and remove 'f' suffixes as XYPOSITION is now double.Neil1-4/+4
2021-05-03Rename Opaque to WithoutAlpha as it returns a colour with 0 alpha. New OpaqueNeil1-1/+5
method returns a colour with maximum (0xff) alpha.
2021-05-01Improve selection drawing code. Use InSelection enum instead of int.Neil5-62/+87
Add Selection::RangeType and EditModel::LineEndInSelection to hoist code out of EditView. Replace SimpleAlphaRectangle with Surface::FillRectangleAligned when alpha known to not be SC_ALPHA_NOALPHA.
2021-04-28Use copy instead of loop and rely on make_unique zeroing result.Neil1-5/+2
2021-04-28More reasonable variable name.Neil1-2/+2
2021-04-28Feature [feature-requests:1373]. Use steady_clock for measuring intervals.Zufu Liu1-4/+4
2021-04-27Rename CharacterSet and CharacterCategory modules in Scintilla to CharacterTypeNeil13-121/+28
and CharacterCategoryMap to avoid clashes with Lexilla when building an executable that includes both.
2021-04-27Feature [feature-requests:1379]. Update to Unicode 13.Neil2-44/+102
2021-04-26Avoid some warnings.Neil7-28/+31
2021-04-26Change std::optional value() to * as value() is not implemented in older macOSNeil Hodgson2-20/+20
releases. Using value() produces error: error: call to unavailable member function 'value': introduced in macOS 10.14
2021-04-26Extract related groups of fields out of ViewStyle into new structs.Neil5-189/+215
Size of ViewStyle makes it more difficult to understand and this helps a bit.
2021-04-26Move hotspotSingleLine from ViewStyle to EditModel as it defines behaviour, notNeil5-7/+6
appearance.
2021-04-25Feature [feature-requests:#1402]. Unify colour type with ColourAlpha.Neil16-272/+251
Change ColourDesired to ColourAlpha in styles. Remove ColourDesired.
2021-04-20Add header to make recent change compile with Xcode.Neil Hodgson1-0/+1
2021-04-20Bug [#2027]. Implement font locale SCI_SETFONTLOCALE on Win32 using DirectWrite.Neil6-7/+34
2021-04-20Feature [feature-requests:#1402]. Unify colour type with ColourAlpha.Neil3-35/+28
Change ColourDesired to ColourAlpha in XPM and RGBAImage.
2021-04-15Bug [#2234]. Remove method that is no longer called.Neil2-5/+0
2021-04-05Mark more destructors as noexcept. Delete unwanted LisboxX standard methods.Neil1-6/+6
2021-04-05Extract unnamed caching enum as LineLayoutCache::Cache and change to enum class.Neil4-21/+23
2021-04-05Extract CharClassify::cc as CharacterClass and change to enum class.Neil5-49/+50
