Many headers from Apple, line the NSTableView, have structs declared containing flags:
This brings me 2 questions:
1.What is this ":1" (or ":2") at the end of each line? I've never seen this!
2.How can I then access this struct from inside object: _TvFlags.(~) or _TvFlags->(~) (dereferenced)
Thanks!
Code:
typedef struct __TvFlags {
unsigned int allowsColumnReordering:1;
unsigned int allowsColumnResizing:1;
unsigned int oldDrawsGridFlag:1;
unsigned int allowsEmptySelection:1;
unsigned int allowsMultipleSelection:1;
unsigned int allowsColumnSelection:1;
unsigned int selectionType:2;
unsigned int changingLayout:1; // Unused
unsigned int compareWidthWithSuperview:2;
unsigned int delegateWillDisplayCell:1;
...
unsigned int delegateShouldEditTableColumn:1;
unsigned int delegateShouldSelectRow:1;
unsigned int delegateShouldSelectTableColumn:1;
unsigned int delegateSelectionShouldChangeInTableView:1;
unsigned int oldAutoresizesAllColumnsToFit:1;
unsigned int dataSourceSetObjectValue:1;
unsigned int selectionPostingDisableCount:7;
} _TvFlags;
