Adjusting the zoom level does not work correctly. It could lead to ever
increasing zoom.
Instead, set the correct DPI of the underlying device context.
Use the same logic for wxGTK (and other platforms using double
buffering) as was already used for wxMac, it seems to result in less
flicker.
Closes#18017.
The SCN_AUTOCSELECTIONCHANGE notification was added in Scintilla 4.0 to
notify an application when a new item is selected in an autocompletion
or user list. However the version of Scintilla currently used is 3.7.2,
so this potentially useful notification is not available.
These changes allow an event corresponding to this notification to be
generated completely in the wxWidgets portion of wxSTC. If the Scintilla
library is ever updated to 4.0 or later, only one method should need to
be modified let Scintilla generate the event instead.
The wxSTC methods AutoCompSetColours and AutoCompUseListCtrl were added
in fe7b332b7b to allow some configuration
of the autocompletion popup window. Based on subsequent discussion, it
was decided that a better method of configuring the popup and getting
information about the configuration is needed. For now, simply remove
the current methods while the better solution is created.
In addition, since the configuration options are being removed, set the
popup to have the appearance of a list control since that was the
appearance before any configuration options were added.
The ScintillaWX::ModifyScrollBars method is used to ensure that the
horizontal and vertical scrollbars are constantly up to date. It
computes the needed max and page size for the scrollbars based on a
combination of input data and internal state variables, compares the
needed values with the scrollbar’s current max and page size, and
updates the scrollbars if there is a difference.
Because of the current logic used, the method will try to update the
scroll bars in two cases where no updates are necessary. First, if a
scrollbar is not visible (or if word wrapping is on for the horizontal
scrollbar), ModifyScrollBars currently tries to set the max to 0.
However on some platforms, such as windows, this call can fail and
result in the max actually being set to 1. Consequently subsequent calls
to ModifyScrollBars will assume the value should be 0 but detect the
scrollbar’s max as 1 and try to update the value again. To avoid this,
instead set the scrollbar’s page size to 1 more than the max.
The second case is only for the horizontal scrollbar. Currently, the
function updates the scrollbar whenever the position is not 0. There
doesn’t seem to be any reason for this check, and so it has simply been
removed.
Closes https://github.com/wxWidgets/wxWidgets/pull/1327
The AutoCompUseListCtrl method can be used to make an autocompletion
list look like it's being shown with a wxListCtrl instead of a
wxListBox. When this style is used, the list will have hot tracking.
On MSW, the colours will also be slightly different.
With some system themes, the default colors used for a list box can be
hard to read or otherwise unsuitable for use with an autocompletion
popup. This method lets a user manually specify colours for the list
box’s background, text, selection background, and selected text.
When switching between call tips in MSW, there can be a bit of flicker
when the first is closed and the new one is opened. To reduce the
flicker, store the call tip background in a bitmap and use a very brief
fade-in animation when showing the new call tip.
Currently the Scintilla message SCI_REGISTERIMAGE is mapped to
wxStyledTextCtrl::RegisterImage(int, const wxBitmap&). This makes
RegisterImage a manually defined method and passes the bitmap directly
to the listbox instead of first converting to an XPM.
To backfill the message map, SCI_REGISTERIMAGE is now mapped to a new
method overload RegisterImage(int, const char* const*). The new method
accepts XPM data instead of a wxBitmap.
Currently the Scintilla message SCI_MARKERDEFINEPIXMAP is mapped to the
wxStyledTextCtrl::MarkerDefineBitmap method. This has two
drawbacks. First this requires the XPM image handler be loaded before
this method can be called. Second, any alpha data except for opaque and
transparent is lost in the conversion to XPM format.
Instead have MarkerDefineBitmap be a manually declared method but
reimplemented it in a way similar to how the SCI_MARKERDEFINERGBAIMAGE
message works. The new implementation preserves alpha data if it exists.
To backfill the message map, the SCI_MARKERDEFINEPIXMAP is now mapped to
a new method MarkerDefinePixmap(int, const char* const*). The new method
accepts XPM data instead of a wxBitmap.
When mouse is captured somwhere in the application, it's recommended
to have implemented a EVT_MOUSE_CAPTURE_LOST handler.
Resetting in the handler flag signalling captured state seems
to be a sufficient action because something like this is implemented
in the native Scintilla and it works fine in SciTE.
Closes#17961.
At least under wxMSW and wxGTK opening a popup menu when mouse is captured
generates EVT_MOUSE_CAPTURE_LOST. We would like to avoid this and
to release capture in a controlled way.
See #17961.
Starting with version 3.5, Scintilla implemented a newer method for
handling timers and used this method in its Windows, GTK+, Cocoa, and Qt
ports. This patch attempts to bring the timer handling for wxSTC in line
with those other ports.
Closes#17949.
Vertical scrollbar didn't appear even when the number of lines in the control
became one greater than the maximal fitting number of lines, but only when one
more line was added.
This seems to have been a simple off-by-one error in SetScrollbar() calls, so
fix this by adding 1 to the upper end of the range.
Closes#17548.
Don't just use wxWX2MBbuf which is just a "const char*" in ANSI build and can
become a dangling pointer if the string it was constructed from was temporary,
as it happens with the string returned by wxStyledTextEvent::GetString().
Closes#17517.
This was broken by bfdf70d14a, so keep one of
the changes done there conditional on the platform to avoid changing behaviour
for the non-Mac ones.
Closes#17251.
The real Ctrl key is represented by "meta" modifier bit under OS X as the
"ctrl" bit is used for the Cmd key, but the previously used KeyDown() method
didn't support the meta bit at all, so key combinations using Ctrl didn't
work.
Also remove obsolete code which mapped "meta" to "ctrl", probably predating
the mapping of Cmd to "ctrl" at wx API level.
See #16243.
At the very least, this avoids tons of gcc warnings about implicit conversions
from float to int and it could also be more correct if the coordinates can
really be fractional.
This avoids excessive CPU load due to generating completely unnecessary timer
notifications for every wxSTC control in a program.
Closes#14938.

These fields were unnecessary and duplicated m_cmdString inherited from the

Also use base class GetString() instead of the redundant GetText() and

backwards compatibility.
