ISSUES & TODO LIST |
|||
|
|||
Issue numbers (#) refer to github issues listed at https://github.com/ocornut/imgui/issues |
|||
The list below consist mostly of ideas noted down before they are requested/discussed by users (at which point it usually moves to the github) |
|||
|
|||
- doc: add a proper documentation+regression testing system (#435) |
|||
- window: add a way for very transient windows (non-saved, temporary overlay over hundreds of objects) to "clean" up from the global window list. perhaps a lightweight explicit cleanup pass. |
|||
- window: calling SetNextWindowSize() every frame with <= 0 doesn't do anything, may be useful to allow (particularly when used for a single axis). (#690) |
|||
- window: auto-fit feedback loop when user relies on any dynamic layout (window width multiplier, column) appears weird to end-user. clarify. |
|||
- window: allow resizing of child windows (possibly given min/max for each axis?.) |
|||
- window: background options for child windows, border option (disable rounding). |
|||
- window: add a way to clear an existing window instead of appending (e.g. for tooltip override using a consistent api rather than the deferred tooltip) > |
|||
- window: resizing from any sides? + mouse cursor directives for app. |
|||
!- window: begin with *p_open == false should return false. |
|||
- window: get size/pos helpers given names (see discussion in #249) |
|||
- window: a collapsed window can be stuck behind the main menu bar? |
|||
- window: when window is small, prioritize resize button over close button. |
|||
- window: detect extra End() call that pop the "Debug" window out and assert at call site instead of later. |
|||
- window/tooltip: allow to set the width of a tooltip to allow TextWrapped() etc. while keeping the height automatic. |
|||
- window: increase minimum size of a window with menus or fix the menu rendering so that it doesn't look odd. |
|||
- draw-list: maintaining bounding box per command would allow to merge draw command when clipping isn't relied on (typical non-scrolling window or non-overflowing column would merge with previous command). |
|||
!- scrolling: allow immediately effective change of scroll after Begin() if we haven't appended items yet |
|||
- splitter/separator: formalize the splitter idiom into an official api (we want to handle n-way split) (#319) |
|||
- widgets: display mode: widget-label, label-widget (aligned on column or using fixed size), label-newline-tab-widget etc. (#395) |
|||
- widgets: clean up widgets internal toward exposing everything. |
|||
- widgets: add disabled and read-only modes (#211) |
|||
- main: considering adding an Init() function? some constructs are awkward in the implementation because of the lack of them. |
|||
!- main: make it so that a frame with no window registered won't refocus every window on subsequent frames (~bump LastFrameActive of all windows). |
|||
- main: IsItemHovered() make it more consistent for various type of widgets, widgets with multiple components, etc. also effectively IsHovered() region sometimes differs from hot region, e.g tree nodes |
|||
- main: IsItemHovered() info stored in a stack? so that 'if TreeNode() { Text; TreePop; } if IsHovered' return the hover state of the TreeNode? |
|||
- input text: clean up the mess caused by converting UTF-8 <> wchar. the code is rather inefficient right now and super fragile. |
|||
- input text: reorganize event handling, allow CharFilter to modify buffers, allow multiple events? (#541) |
|||
- input text: expose CursorPos in char filter event (#816) |
|||
- input text: flag to disable live update of the user buffer (also applies to float/int text input) |
|||
- input text: resize behavior - field could stretch when being edited? hover tooltip shows more text? |
|||
- input text: add ImGuiInputTextFlags_EnterToApply? (off #218) |
|||
- input text: add discard flag (e.g. ImGuiInputTextFlags_DiscardActiveBuffer) or make it easier to clear active focus for text replacement during edition (#725) |
|||
- input text multi-line: don't directly call AddText() which does an unnecessary vertex reserve for character count prior to clipping. and/or more line-based clipping to AddText(). and/or reorganize TextUnformatted/RenderText for more efficiency for large text (e.g TextUnformatted could clip and log separately, etc). |
|||
- input text multi-line: way to dynamically grow the buffer without forcing the user to initially allocate for worse case (follow up on #200) |
|||
- input text multi-line: line numbers? status bar? (follow up on #200) |
|||
- input text multi-line: behave better when user changes input buffer while editing is active (even though it is illegal behavior). namely, the change of buffer can create a scrollbar glitch (#725) |
|||
- input text multi-line: better horizontal scrolling support (#383, #1224) |
|||
- input text: allow centering/positioning text so that ctrl+clicking Drag or Slider keeps the textual value at the same pixel position. |
|||
- input number: optional range min/max for Input*() functions |
|||
- input number: holding [-]/[+] buttons could increase the step speed non-linearly (or user-controlled) |
|||
- input number: use mouse wheel to step up/down |
|||
- input number: applying arithmetics ops (+,-,*,/) messes up with text edit undo stack. |
|||
- button: provide a button that looks framed. |
|||
- text: proper alignment options |
|||
- image/image button: misalignment on padded/bordered button? |
|||
- image/image button: parameters are confusing, image() has tint_col,border_col whereas imagebutton() has bg_col/tint_col. Even thou they are different parameters ordering could be more consistent. can we fix that? |
|||
- layout: horizontal layout helper (#97) |
|||
- layout: horizontal flow until no space left (#404) |
|||
- layout: more generic alignment state (left/right/centered) for single items? |
|||
- layout: clean up the InputFloatN/SliderFloatN/ColorEdit4 layout code. item width should include frame padding. |
|||
- layout: BeginGroup() needs a border option. |
|||
- columns: declare column set (each column: fixed size, %, fill, distribute default size among fills) (#513, #125) |
|||
- columns: add a conditional parameter to SetColumnOffset() (#513, #125) |
|||
- columns: separator function or parameter that works within the column (currently Separator() bypass all columns) (#125) |
|||
- columns: columns header to act as button (~sort op) and allow resize/reorder (#513, #125) |
|||
- columns: user specify columns size (#513, #125) |
|||
- columns: flag to add horizontal separator above/below? |
|||
- columns/layout: setup minimum line height (equivalent of automatically calling AlignFirstTextHeightToWidgets) |
|||
- combo: sparse combo boxes (via function call?) / iterators |
|||
- combo: contents should extends to fit label if combo widget is small |
|||
- combo/listbox: keyboard control. need InputText-like non-active focus + key handling. considering keyboard for custom listbox (pr #203) |
|||
- listbox: multiple selection |
|||
- listbox: user may want to initial scroll to focus on the one selected value? |
|||
- listbox: keyboard navigation. |
|||
- listbox: scrolling should track modified selection. |
|||
!- popups/menus: clarify usage of popups id, how MenuItem/Selectable closing parent popups affects the ID, etc. this is quite fishy needs improvement! (#331, #402) |
|||
- popups: add variant using global identifier similar to Begin/End (#402) |
|||
- popups: border options. richer api like BeginChild() perhaps? (#197) |
|||
- tooltip: tooltip that doesn't fit in entire screen seems to lose their "last preferred button" and may teleport when moving mouse |
|||
- menus: local shortcuts, global shortcuts (#456, #126) |
|||
- menus: icons |
|||
- menus: menubars: some sort of priority / effect of main menu-bar on desktop size? |
|||
- menus: calling BeginMenu() twice with a same name doesn't seem to append nicely |
|||
- statusbar: add a per-window status bar helper similar to what menubar does. |
|||
- tabs (#261, #351) |
|||
- separator: separator on the initial position of a window is not visible (cursorpos.y <= clippos.y) |
|||
!- color: the color helpers/typing is a mess and needs sorting out. |
|||
- node/graph editor (#306) |
|||
- pie menus patterns (#434) |
|||
- drag'n drop, dragging helpers (carry dragging info, visualize drag source before clicking, drop target, etc.) (#143, #479) |
|||
- plot: PlotLines() should use the polygon-stroke facilities (currently issues with averaging normals) |
|||
- plot: make it easier for user to draw extra stuff into the graph (e.g: draw basis, highlight certain points, 2d plots, multiple plots) |
|||
- plot: "smooth" automatic scale over time, user give an input 0.0(full user scale) 1.0(full derived from value) |
|||
- plot: add a helper e.g. Plot(char* label, float value, float time_span=2.0f) that stores values and Plot them for you - probably another function name. and/or automatically allow to plot ANY displayed value (more reliance on stable ID) |
|||
- slider: allow using the [-]/[+] buttons used by InputFloat()/InputInt() |
|||
- slider: initial absolute click is imprecise. change to relative movement slider (same as scrollbar). |
|||
- slider: add dragging-based widgets to edit values with mouse (on 2 axises), saving screen real-estate. |
|||
- slider: tint background based on value (e.g. v_min -> v_max, or use 0.0f either side of the sign) |
|||
- slider & drag: int data passing through a float |
|||
- drag float: up/down axis |
|||
- drag float: added leeway on edge (e.g. a few invisible steps past the clamp limits) |
|||
- tree node / optimization: avoid formatting when clipped. |
|||
- tree node: tree-node/header right-most side doesn't take account of horizontal scrolling. |
|||
- tree node: add treenode/treepush int variants? not there because (void*) cast from int warns on some platforms/settings? |
|||
- tree node: try to apply scrolling at time of TreePop() if node was just opened and end of node is past scrolling limits? |
|||
- tree node / selectable render mismatch which is visible if you use them both next to each other (e.g. cf. property viewer) |
|||
- tree node: tweak color scheme to distinguish headers from selected tree node (#581) |
|||
- textwrapped: figure out better way to use TextWrapped() in an always auto-resize context (tooltip, etc.) (#249) |
|||
- settings: write more decent code to allow saving/loading new fields |
|||
- settings: api for per-tool simple persistent data (bool,int,float,columns sizes,etc.) in .ini file |
|||
- stb: add defines to disable stb implementations |
|||
- style: add window shadows. |
|||
- style/optimization: store rounded corners in texture to use 1 quad per corner (filled and wireframe) to lower the cost of rounding. |
|||
- style: color-box not always square? |
|||
- style: a concept of "compact style" that the end-user can easily rely on (e.g. PushStyleCompact()?) that maps to other settings? avoid implementing duplicate helpers such as SmallCheckbox(), etc. |
|||
- style: try to make PushStyleVar() more robust to incorrect parameters (to be more friendly to edit & continues situation). |
|||
- style: global scale setting. |
|||
- style: WindowPadding needs to be EVEN as the 0.5 multiplier used on this value probably have a subtle effect on clip rectangle |
|||
- text: simple markup language for color change? |
|||
- font: dynamic font atlas to avoid baking huge ranges into bitmap and make scaling easier. |
|||
- font: small opt: for monospace font (like the defalt one) we can trim IndexXAdvance as long as trailing value is == FallbackXAdvance |
|||
- font: add support for kerning, probably optional. perhaps default to (32..128)^2 matrix ~ 36KB then hash fallback. |
|||
- font: add a simpler CalcTextSizeA() api? current one ok but not welcome if user needs to call it directly (without going through ImGui::CalcTextSize) |
|||
- font: fix AddRemapChar() to work before font has been built. |
|||
- log: LogButtons() options for specifying depth and/or hiding depth slider |
|||
- log: have more control over the log scope (e.g. stop logging when leaving current tree node scope) |
|||
- log: be able to log anything (e.g. right-click on a window/tree-node, shows context menu? log into tty/file/clipboard) |
|||
- log: let user copy any window content to clipboard easily (CTRL+C on windows? while moving it? context menu?). code is commented because it fails with multiple Begin/End pairs. |
|||
- filters: set a current filter that tree node can automatically query to hide themselves |
|||
- filters: handle wildcards (with implicit leading/trailing *), regexps |
|||
- filters: fuzzy matches (may use code at blog.forrestthewoods.com/4cffeed33fdb) |
|||
- shortcuts: add a shortcut api, e.g. parse "&Save" and/or "Save (CTRL+S)", pass in to widgets or provide simple ways to use (button=activate, input=focus) |
|||
!- keyboard: tooltip & combo boxes are messing up / not honoring keyboard tabbing |
|||
- keyboard: full keyboard navigation and focus. (#323) |
|||
- focus: preserve ActiveId/focus stack state, e.g. when opening a menu and close it, previously selected InputText() focus gets restored (#622) |
|||
- focus: SetKeyboardFocusHere() on with >= 0 offset could be done on same frame (else latch and modulate on beginning of next frame) |
|||
- input: rework IO system to be able to pass actual ordered/timestamped events. (~#335, #71) |
|||
- input: allow to decide and pass explicit double-clicks (e.g. for windows by the CS_DBLCLKS style). |
|||
- input: support track pad style scrolling & slider edit. |
|||
- misc: provide a way to compile out the entire implementation while providing a dummy API (e.g. #define IMGUI_DUMMY_IMPL) |
|||
- misc: double-clicking on title bar to minimize isn't consistent, perhaps move to single-click on left-most collapse icon? |
|||
- misc: provide HoveredTime and ActivatedTime to ease the creation of animations. |
|||
- style editor: have a more global HSV setter (e.g. alter hue on all elements). consider replacing active/hovered by offset in HSV space? (#438) |
|||
- style editor: color child window height expressed in multiple of line height. |
|||
- remote: make a system like RemoteImGui first-class citizen/project (#75) |
|||
- drawlist: move Font, FontSize, FontTexUvWhitePixel inside ImDrawList and make it self-contained (apart from drawing settings?) |
|||
- drawlist: end-user probably can't call Clear() directly because we expect a texture to be pushed in the stack. |
|||
- examples: directx9: save/restore device state more thoroughly. |
|||
- examples: window minimize, maximize (#583) |
|||
- optimization: add clipping for multi-component widgets (SliderFloatX, ColorEditX, etc.). one problem is that nav branch can't easily clip parent group when there is a move request. |
|||
- optimization: add a flag to disable most of rendering, for the case where the user expect to skip it (#335) |
|||
- optimization: use another hash function than crc32, e.g. FNV1a |
|||
- optimization/render: merge command-lists with same clip-rect into one even if they aren't sequential? (as long as in-between clip rectangle don't overlap)? |
|||
- optimization: turn some the various stack vectors into statically-sized arrays |
