AppendFracZero()

static void AppendFracZero ( char * text, std::size_t textCap, Int_t digits )

static

Given a numeric string "xxx.yyy" or "xxx,yyy", makes sure that the fractional part (if present) always has at least digits digits, appending zeroes if needed.

Definition at line 574 of file TGNumberEntry.cxx.

CheckMinMax()

static void CheckMinMax ( Long_t & l, TGNumberFormat::EStyle style, TGNumberFormat::ELimit limits, Double_t min, Double_t max )

static

Check min/max limits for the set value.

Definition at line 786 of file TGNumberEntry.cxx.

CopyAndSkipGarbage()

static void CopyAndSkipGarbage ( char * dst, std::size_t dstCap, const char * src, TGNumberFormat::EStyle style, TGNumberFormat::EAttribute attr )

static

Copy the string stored in src into dst, skipping some chars depending on the format and style.

The copy is stopped when reaching dstCap-1 copied chars or when finding a null terminator char in src, whatever happens first.

Parameters

src	(owned by caller) is the preallocated char buffer to be copied
dst	(owned by caller) is a preallocated char buffer where result is stored
dstCap	must match the length of dst buffer and be bigger than 0
style	see TGNumberFormat::EStyle
attr	see TGNumberFormat::EAttribute

Note

If src is a nullptr, this function is a no-op and returns silently
