@ -77,6 +77,57 @@ Other changes:
Disabling this was previously possible for Selectable() via a direct flag but not for MenuItem().
(#1379, #1468, #2200, #4936, #5216, #7302, #7573)
- This was mostly all previously in imgui_internal.h.
- Multi-Select: added multi-select API and demos. (#1861)
- This system implements standard multi-selection idioms (CTRL+mouse click, CTRL+keyboard moves,
SHIFT+mouse click, SHIFT+keyboard moves, etc.) with support for clipper (not submitting non-visible
items), box-selection with scrolling, and many other details.
- In the spirit of Dear ImGui design, your code owns both items and actual selection data.
This is designed to allow all kinds of selection storage you may use in your application
(e.g. set/map/hash, intrusive selection, interval trees, up to you).
- The supported widgets are Selectable(), Checkbox(). TreeNode() is also technically supported but...
using this correctly is more complicated (you need some sort of linear/random access to your tree,
which is suited to advanced trees setups already implementing filters and clipper.
We will work toward simplifying and demoing this later.
- A helper ImGuiSelectionBasicStorage is provided to facilitate getting started in a typical app.
- Documentation:
- Wiki page https://github.com/ocornut/imgui/wiki/Multi-Select for API overview.
- Demo code.
- Headers are well commented.
- Added BeginMultiSelect(), EndMultiSelect(), SetNextItemSelectionUserData().
- Added IsItemToggledSelection() for use if you need latest selection update during currnet iteration.
- Added ImGuiMultiSelectIO and ImGuiSelectionRequest structures:
- BeginMultiSelect() and EndMultiSelect() return a ImGuiMultiSelectIO structure, which
is mostly an array of ImGuiSelectionRequest actions (clear, select all, set range, etc.)
- Other fields are helpful when using a clipper, or wanting to handle deletion nicely.
- Added ImGuiSelectionBasicStorage helper to store and maintain a selection (optional):
- This is similar to if you used e.g. a std::set<ID> to store a selection, with all the right
glue to honor ImGuiMultiSelectIO requests. Most applications can use that.
- Added ImGuiSelectionExternalStorage helper to maintain an externally stored selection (optional):
- Helpful to easily bind multi-selection to e.g. an array of checkboxes.
- Added ImGuiMultiSelectFlags options:
- ImGuiMultiSelectFlags_SingleSelect
- ImGuiMultiSelectFlags_NoSelectAll
- ImGuiMultiSelectFlags_NoRangeSelect
- ImGuiMultiSelectFlags_NoAutoSelect
- ImGuiMultiSelectFlags_NoAutoClear
- ImGuiMultiSelectFlags_NoAutoClearOnReselect (#7424)
- ImGuiMultiSelectFlags_BoxSelect1d
- ImGuiMultiSelectFlags_BoxSelect2d
- ImGuiMultiSelectFlags_BoxSelectNoScroll
- ImGuiMultiSelectFlags_ClearOnEscape
- ImGuiMultiSelectFlags_ClearOnClickVoid
- ImGuiMultiSelectFlags_ScopeWindow (default), ImGuiMultiSelectFlags_ScopeRect
- ImGuiMultiSelectFlags_SelectOnClick (default), ImGuiMultiSelectFlags_SelectOnClickRelease
- ImGuiMultiSelectFlags_NavWrapX
- Demo: Added "Examples->Assets Browser" demo.
- Demo: Added "Widgets->Selection State & Multi-Select" section, with:
- Multi-Select
- Multi-Select (with clipper)
- Multi-Select (with deletion)
- Multi-Select (dual list box) (#6648)
- Multi-Select (checkboxes)
- Multi-Select (multiple scopes)
- Multi-Select (advanced)
- Clipper: added SeekCursorForItem() function. When using ImGuiListClipper::Begin(INT_MAX) you can
can use the clipper without knowing the amount of items beforehand. (#1311)
In this situation, call ImGuiListClipper::SeekCursorForItem(items_count) as the end of your iteration

// Documentation at: https://github.com/ocornut/imgui/wiki/Multi-Select

// - This system implements standard multi-selection idioms (CTRL+Mouse/Keyboard, SHIFT+Mouse/Keyboard, etc)
// with support for clipper (skipping non-visible items), box-select and many other details.
// - Selectable(), Checkbox() are supported but custom widgets may use it as well.

// - In the spirit of Dear ImGui design, your code owns actual selection data.
// This is designed to allow all kinds of selection storage you may use in your application e.g. set/map/hash.
// About ImGuiSelectionBasicStorage:
// - This is an optional helper to store a selection state and apply selection requests.
// - It is used by our demos and provided as a convenience to quickly implement multi-selection.
// Usage:
// - Identify submitted items with SetNextItemSelectionUserData(), most likely using an index into your current data-set.
// - Store and maintain actual selection data using persistent object identifiers.
// - Usage flow:
// BEGIN - (1) Call BeginMultiSelect() and retrieve the ImGuiMultiSelectIO* result.
// - (2) Honor request list (SetAll/SetRange requests) by updating your selection data. Same code as Step 6.
// - (3) [If using clipper] You need to make sure RangeSrcItem is always submitted. Calculate its index and pass to clipper.IncludeItemByIndex(). If storing indices in ImGuiSelectionUserData, a simple clipper.IncludeItemByIndex(ms_io->RangeSrcItem) call will work.
// LOOP - (4) Submit your items with SetNextItemSelectionUserData() + Selectable()/TreeNode() calls.
// END - (5) Call EndMultiSelect() and retrieve the ImGuiMultiSelectIO* result.
// - (6) Honor request list (SetAll/SetRange requests) by updating your selection data. Same code as Step 2.
// If you submit all items (no clipper), Step 2 and 3 are optional and will be handled by each item themselves. It is fine to always honor those steps.
// About ImGuiSelectionUserData:
// - This can store an application-defined identifier (e.g. index or pointer) submitted via SetNextItemSelectionUserData().
// - In return we store them into RangeSrcItem/RangeFirstItem/RangeLastItem and other fields in ImGuiMultiSelectIO.
// - Most applications will store an object INDEX, hence the chosen name and type. Storing an index is natural, because
// SetRange requests will give you two end-points and you will need to iterate/interpolate between them to update your selection.
// - However it is perfectly possible to store a POINTER or another IDENTIFIER inside ImGuiSelectionUserData.
// Our system never assume that you identify items by indices, it never attempts to interpolate between two values.
// - As most users will want to store an index, for convenience and to reduce confusion we use ImS64 instead of void*,
// being syntactically easier to downcast. Feel free to reinterpret_cast and store a pointer inside.

// Optional helper to store multi-selection state + apply multi-selection requests.
// - Used by our demos and provided as a convenience to easily implement basic multi-selection.
// - Iterate selection with 'void* it = NULL; ImGuiID id; while (selection.GetNextSelectedItem(&it, &id)) { ... }'
// Or you can check 'if (Contains(id)) { ... }' for each possible object if their number is not too high to iterate.
// - USING THIS IS NOT MANDATORY. This is only a helper and not a required API.
// To store a multi-selection, in your application you could:
// - Use this helper as a convenience. We use our simple key->value ImGuiStorage as a std::set<ImGuiID> replacement.
// - Use your own external storage: e.g. std::set<MyObjectId>, std::vector<MyObjectId>, interval trees, intrusively stored selection etc.
// In ImGuiSelectionBasicStorage we:
// - always use indices in the multi-selection API (passed to SetNextItemSelectionUserData(), retrieved in ImGuiMultiSelectIO)
// - use the AdapterIndexToStorageId() indirection layer to abstract how persistent selection data is derived from an index.
// - use decently optimized logic to allow queries and insertion of very large selection sets.
// - do not preserve selection order.
// Many combinations are possible depending on how you prefer to store your items and how you prefer to store your selection.
// Large applications are likely to eventually want to get rid of this indirection layer and do their own thing.
// See https://github.com/ocornut/imgui/wiki/Multi-Select for details and pseudo-code using this helper.
