On DC with a non-rotated coordinate system drawing a filled rectangle with ExtTextOut() Win API is faster than drawing a line with MoveTo()/LineTo() so on such DCs we can use ExtTextOut() to draw horizontal/vertical lines with solid colors and square ends instead of calling MoveTo()/LineTo().
See #18517.
Setting WS_EX_COMPOSITED, as the base class version does, just results
in visual artefacts and is useless, as we turn on LVS_EX_DOUBLEBUFFER
already, if it's supported, anyhow.
So don't break the display if people call SetDoubleBuffered() in the
mistaken belief that it does something useful in this case.
Adjust the length limit before pasting to ensure that all text on
clipboard will be successfully pasted, instead of only pasting the part
of it which fits.
Add a unit test checking that this works.
Closes#4646.
These control are drawn using a wxDC. When the DPI changes, call SetFont
to update the font of the wxDC. First call wxListBoxBase::SetFont() so
m_font is updated to the new DPI, then use this font in the wxDC.
For wxCheckListBox update the margins to fit the changed checkbox size.
The control seems to somehow react to DPI changes on its own (which is
rather mysterious as we don't forward WM_DPICHANGED to it, so it's not
really clear how does it do it, but it does) and changing its font is
worse than useless, as it's not just redundant, but also resets all the
styles used inside the control and so is really undesirable.
Hence override the just added MSWUpdateFontOnDPIChange() to do nothing
for rich edit controls, while still updating the font for the plain EDIT
ones (which is required as they don't scale correctly on their own).
Fix position of spin control in wxSpinCtrlDouble after DPI change
The old size of the control was used to determine the position. Use GetBestSize
instead, which will return the correct size.
Some native dialogs do not scale correctly (color picker, font picker,
open file with custom controls). ALl other native dialogs do scale correctly
(open file, open directory, find replace, print).
Change the DPI Awareness Context temporarily to SystemAware, so Windows handles
the scaling.
For 32 bpp wxBitmap with both alpha channel and mask we have to apply mask on our own while drawing the bitmap because MaskBlt() API doesn't work properly with 32 bpp RGBA bitmaps. To do so we need to create a temporary bitmap with copy of original RGB data and with alpha channel being a superposition of the original alpha values and the mask.
See #18498.
Update the font of some buddy controls when the DPI changes. Fix the
position of the statusbar after a DPI change. Add some changes that were
suggested in https://github.com/wxWidgets/wxWidgets/pull/1499 but left
out from it.
Some sizes are cached to improve the speed of the library. These sizes
become incorrect when the DPI changes. And are incorrect when a window
is created on a display with a different DPI. Fix this by checking if
the current DPI is the same as the DPI that was used when calculating
the size, otherwise recalculate the size.
Closes https://github.com/wxWidgets/wxWidgets/pull/1530
Due to lack of support for horizontal scrolling in the native control,
scrolling it was implementing by offsetting the entire control window.
However this didn't work correctly when the window was not positioned
at the leftmost border of its parent window, as the part of it that was
scrolled off could still be visible in this case, and this is exactly
what happened when the native header was used in wxGrid: scrolling it
overwrote the corner part of wxGrid.
Fix this by embedding the actual native control inside an outer wxWindow,
to ensure that the scrolled off part is clipped by the parent window.
Note that this commit is best viewed with "git show --color-moved" as
most of the code was just moved from the header into the implementation
file and is not really new.
Add preliminary support for per-monitor DPI awareness to wxMSW.
Individual controls still need to be fixed, so this support is still
experimental/unfinished for now.
See https://github.com/wxWidgets/wxWidgets/pull/1499
React to the WM_DPICHANGED event and update the size of the child windows and
the top-level window. Scale the minimum and maximum window size to the new DPI.
Only react to WM_DPICHANGED when DPI_AWARENESS_CONTEXT_PER_MONITOR_AWARE_V2 is
used.
This is simpler to use than wxDisplay(window).GetPPI() which was used
instead of it so far in all ports and can be implemented more
efficiently for wxMSW.
Remove wxGetWinTLW, GetDPI already tries to get the top window.
Draw the same shape in wxDC::DrawCheckMark() under all platforms and
provide wxRenderer::DrawCheckMark() for drawing the platform-specific
shape.
Also fix wxGCDC::DrawPoint() to use the default one point wide pen.
See https://github.com/wxWidgets/wxWidgets/pull/1471
Ensure that the new colours are actually shown after Refresh() is called
by refreshing the text part of the control as well, and not just the
spin button.
Closes https://github.com/wxWidgets/wxWidgets/pull/1468Closes#12382.
Add MSWDoClientToScreen() and MSWDoScreenToClient() helpers and use them
with the correct HWND in DoClientToScreen() and DoScreenToClient()
overridden in wxSpinCtrl, i.e. the HWND of the "buddy" text control and
not the spin button, which is the main HWND of this control.
This notably fixes wxSpinCtrl::GetScreenPosition() which returned the
position of the spin button.
Closes https://github.com/wxWidgets/wxWidgets/pull/1454Closes#18455.
Even though these functions were declared in a header called private.h,
some code outside the library still used them, notably the popular
wxPdfDocument library.
So partially revert 72a225924d and these
functions back, and just mark them as deprecated for now.
This parameter is not modified by wxColourDialog (this might have been
the case, or at least the plan, some long time ago) and so has no reason
not to be "const".
Just add the qualifier to ctor and Create() in all ports.
Closes https://github.com/wxWidgets/wxWidgets/pull/1421Closes#12511.
These metrics can change when the DPI of a Window changes, so we can not keep a
static reference.
According to documentation, the second parameter (uiParam) should be set to the
size of the NONCLIENTMETRICS object.
