Felix14-v2's review of OrcaSlicer#16019 found the tab behaving as a world of its own.
- Icons: the design_* glyphs were drawn in a fixed light grey, made for the dark ribbon, and the
toolbar re-tinted some of them by rebuilding the bitmap from a wxImage, which drops the HiDPI
scale factor Orca sets on Windows: at 150 % the icons came out half again too large for buttons
that were sized in raw pixels, overlapping and clipped. The glyphs now use Orca's sidebar icon
grey (#949494), which the icon cache maps per theme, nothing is re-tinted, toolbar glyphs drawn
for Prepare's light toolbar use their "_dark" twin, and every size is in DIP.
- Theme: the chrome colours were read once, at construction, and nothing in the tab answered a
theme switch, so switching left light surfaces and unreadable text in a dark tab and the other
way round. The colours are now {light, dark} token pairs; MainFrame::on_sys_color_changed
reaches DesignPanel::on_sys_color_changed, which moves every token colour onto the other
theme's, runs the app's dark pass and re-rasterises the icons. Card borders are StateColors,
resolved at paint time.
- Scale: MainFrame::on_dpi_changed reaches DesignPanel::msw_rescale, which re-rasterises every
icon (buttons, flyout rows, card headers, the tree's image list, now sized from its bitmaps)
and re-measures the Orca widgets.
- Mouse: the canvas no longer forces middle-drag to orbit and right-drag to pan; it reads the
drag actions in Preferences > Control like Prepare. Left-drag is shared with picking, so the
whole-body rubber band takes Shift+left-drag while left-drag is given to the camera.
- FPS counter: ImGui's display size is shared and only refreshed when a canvas sees its own
size change; the Design canvas now re-announces its size when the tab is entered (and the
editor canvas when it is left), as Plater does between Prepare and Preview.
- Viewport text: the status line and the tool readout were top-level popups over GL. A popup
does not follow its frame, so the empty-canvas hint floated over other applications, and the
readout was never taken down with the tab. Both are drawn by the canvas in the tool's ImGui
pass now, with the theme's overlay style.
- Dialogs: messages use MessageDialog/RichMessageDialog; Add/Edit Variable is one Orca dialog
with Name and Expression fields instead of two native text prompts; the Text dialog uses
TextInput, ComboBox and CheckBox (its height is a TextInput: SpinInput is integer-only), and
enumerates the installed fonts once per session. The ribbon's Confirm/Cancel, the reference
pick buttons and the expression buttons are Orca Buttons; the variable actions are icon
buttons like the other cards'.
- Undo: the tab's own Undo/Redo buttons are gone. The top bar's Undo/Redo drive the Design
history while the tab is shown, greyed to what an undo would do, as Ctrl+Z and Edit already
did.
- The first build of the tab logs how long each phase took ("Design tab build: ..."): it is
under a second here but was reported at about fifteen on Windows.
