Refactor: Tweaked and improved the sectioning to facilitate grepping/moving around and applied to all files. (#2036)
2018-09-06 09:35:13 +00:00
// [SECTION] STB libraries implementation
// [SECTION] Style functions
// [SECTION] ImDrawList
ImDrawList: add PathFillConcave(), AddConcavePolyFilled(): amends (#760) - Simplify and compact some code. Shallow tweaks. - Add comments. - Add concave shape demo. - Remove coarse culling. - Remove nested types to match coding style and for consistent type nams when translated to other languages. - Merged ClassifyNode() and ReclassifyNode(). - Extracted ImTriangleIsClockwise(). - Hold copy of points inside nodes instead of pointing to them.
2024-01-09 22:36:26 +00:00
// [SECTION] ImTriangulator, ImDrawList concave polygon fill
ImDrawListSplitter: extracted out of ImDrawList. Down the line we may obsolete the ImDrawList functions and encourage users to store the splitter aside, in the meanwhile ImDrawList holds a splitter. (This will allow columns/table to recurse.)

Windows, Internal: added experimental SkipRefresh mode. (#3515, #4763, #7556, #5116 , #4076, #2749, #2268) currently: ImGui::SetNextWindowRefreshPolicy(ImGuiWindowRefreshFlags_TryToAvoidRefresh); - This is NOT meant to replace frame-wide/app-wide idle mode. - This is another tool: the idea that a given window could avoid refresh and reuse last frame contents. - I think it needs to be backed by a careful and smart design overall (refresh policy, load balancing, making it easy and obvious to user). - It's not there yet, this is currently a toy for experimenting. My other issues with this: - It appears to be very simple, but skipping most of Begin() logic will inevitably lead to tricky/confusing bugs. Let's see how it goes. - I don't like very much that this opens a door to varying inconsistencies - I don't like very much that it can lead us to situation where the lazy refresh gets disabled in bulk due to some reason (e.g. resizing a dock space) and we get sucked in the temptation to update for idle rather than update for dynamism.

Add MouseWindowID + change SDL_CaptureMouse() test to match docking branch. Not strictly necessary but aimed at reducing drift because we go on and fork this file. + moved responsability of checking valid names to TabBarGetTabName() to simplify both branches.

ImDrawList: Added ImDrawCmd::VtxOffset value to support large meshes (64k+ vertices) using 16-bits indices. To enable the feature, the renderer back-end needs to set 'io.BackendFlags |= ImGuiBackendFlags_HasVtxOffset' and honor the ImDrawCmd::VtxOffset field. Otherwise the value will always be zero. This has the advantage of preserving smaller index buffers and allowing to execute on hardware that do not support 32-bits indices. ImDrawList: Added ImDrawCmd::IdxOffset value, equivalent to summing element count for each draw command. This is provided for convenience and consistency with VtxOffset. (#2591)

// - We intentionally avoid using ImVec2 and its math operators here to reduce cost to a minimum for debug/non-inlined builds.
// - Filled shapes must always use clockwise winding order. The anti-aliasing fringe depends on it. Counter-clockwise shapes will have "inward" anti-aliasing.

// glDrawElements(GL_TRIANGLES, (GLsizei)pcmd->ElemCount, sizeof(ImDrawIdx) == 2 ? GL_UNSIGNED_SHORT : GL_UNSIGNED_INT, idx_buffer_offset);

// Helper to scale the ClipRect field of each ImDrawCmd.

ImDrawData: Added FramebufferScale field (currently a copy of the value from io.DisplayFramebufferScale). This is to allow render functions being written without pulling any data from ImGuiIO, allowing incoming multi-viewport feature to behave on Retina display and with multiple displays. If you are not using a custom binding, please update your render function code ahead of time, and use draw_data->FramebufferScale instead of io.DisplayFramebufferScale. (#2306, #1676) Examples: Metal, OpenGL2, OpenGL3: Fixed offsetting of clipping rectangle with ImDrawData::DisplayPos != (0,0) when the display frame-buffer scale scale is not (1,1). While this doesn't make a difference when using master branch, this is effectively fixing support for multi-viewport with Mac Retina Displays on those examples. (#2306) Also using ImDrawData::FramebufferScale instead of io.DisplayFramebufferScale. Examples: Clarified the use the ImDrawData::DisplayPos to offset clipping rectangles.

Font: implement a way to draw narrow ellipsis without relying on hardcoded 1 pixel dots. (#2775) This changeset implements several pieces of the puzzle that add up to a narrow ellipsis rendering. ## EllipsisCodePoint `ImFontConfig` and `ImFont` received `ImWchar EllipsisCodePoint = -1;` field. User may configure `ImFontConfig::EllipsisCodePoint` a unicode codepoint that will be used for rendering narrow ellipsis. Not setting this field will automatically detect a suitable character or fall back to rendering 3 dots with minimal spacing between them. Autodetection prefers codepoint 0x2026 (narrow ellipsis) and falls back to 0x0085 (NEXT LINE) when missing. Wikipedia indicates that codepoint 0x0085 was used as ellipsis in some older windows fonts. So does default Dear ImGui font. When user is merging fonts - first configured and present ellipsis codepoint will be used, ellipsis characters from subsequently merged fonts will be ignored. ## Narrow ellipsis Rendering a narrow ellipsis is surprisingly not straightforward task. There are cases when ellipsis is bigger than the last visible character therefore `RenderTextEllipsis()` has to hide last two characters. In a subset of those cases ellipsis is as big as last visible character + space before it. `RenderTextEllipsis()` tries to work around this case by taking free space between glyph edges into account. Code responsible for this functionality is within `if (text_end_ellipsis != text_end_full) { ... }`. ## Fallback (manually rendered dots) There are cases when font does not have ellipsis character defined. In this case RenderTextEllipsis() falls back to rendering ellipsis as 3 dots, but with reduced spacing between them. 1 pixel space is used in all cases. This results in a somewhat wider ellipsis, but avoids issues where spaces between dots are uneven (visible in larger/monospace fonts) or squish dots way too much (visible in default font where dot is essentially a pixel). This fallback method obsoleted `RenderPixelEllipsis()` and this function was removed. Note that fallback ellipsis will always be somewhat wider than it could be, however it will fit in visually into every font used unlike what `RenderPixelEllipsis()` produced.
