boolRequestSetRange;// / / ms:w, app:r // 3. Request app/user to select/unselect [RangeSrcItem..RangeDstItem] items, based on RangeSelected. In practice, only EndMultiSelect() request this, app code can read after BeginMultiSelect() and it will always be false.
boolRequestSetRange;// / / ms:w, app:r // 3. Request app/user to select/unselect [RangeFirstItem..RangeLastItem] items, based on RangeSelected. Only EndMultiSelect() request this, app code can read after BeginMultiSelect() and it will always be false.
ImGuiSelectionUserDataRequestFocusItem;// app:w / app:r / app:r // (If using deletion) 4. Request user to focus item. This is actually only manipulated in user-space, but we provide storage to facilitate implementing a deletion idiom (see demo).
// STATE/ARGUMENTS -------------------------// BEGIN / LOOP / END
ImGuiSelectionUserDataRangeSrcItem;// ms:w / app:r / ms:w, app:r // Begin: Last known SetNextItemSelectionUserData() value for RangeSrcItem. End: parameter from RequestSetRange request.
ImS8RangeDirection;// / / ms:w, app:r // End: parameter from RequestSetRange request. +1 if RangeSrcItem came before RangeDstItem, -1 otherwise. Available as an indicator in case you cannot infer order from the void* values. If your void* values are storing indices you will never need this.
ImGuiSelectionUserDataRangeSrcItem;// ms:w / app:r / // (If using clipper) Begin: Source item (generally the first selected item when multi-selecting, which is used as a reference point). Read during loop in order for user code to set RangeSrcPassedBy.
ImGuiSelectionUserDataRangeFirstItem;// / / ms:w, app:r // End: parameter for RequestSetRange request (this is generally == RangeSrcItem when shift selecting from top to bottom)
ImGuiSelectionUserDataRangeLastItem;// / / ms:w, app:r // End: parameter for RequestSetRange request (this is generally == RangeSrcItem when shift selecting from bottom to top)
boolRangeSrcPassedBy;// / ms:rw app:w / ms:r // (If using clipper) Need to be set by app/user if RangeSrcItem was part of the clipped set before submitting the visible items. Ignore if not clipping.
boolRangeSrcReset;// app:w / app:w / ms:r // (If using deletion) Set before EndMultiSelect() to reset ResetSrcItem (e.g. if deleted selection).
boolNavIdSelected;// ms:w, app:r / / // (If using deletion) Last known selection state for NavId (if part of submitted items).
ImGuiSelectionUserDataNavIdItem;// ms:w, app:r / / // (If using deletion) Last known SetNextItemSelectionUserData() value for NavId (if part of submitted items).
// you will need a way to iterate from one item to the other item given the ID you use.
// You are likely to need some kind of data structure to convert 'view index' <> 'object ID' (FIXME-MULTISELECT: Would be worth providing a demo of doing this).
// Note: This implementation of SetRange() is inefficient because it doesn't take advantage of the fact that ImGuiStorage stores sorted key.
voidSelectAll(intcount){Storage.Data.resize(count);for(intidx=0;idx<count;idx++)Storage.Data[idx]=ImGuiStoragePair((ImGuiID)idx,1);SelectionSize=count;}// This could be using SetRange(), but it this way is faster.
// Apply requests coming from BeginMultiSelect() and EndMultiSelect(). Must be done in this order! Clear->SelectAll->SetRange.
