2017-04-23 Markus Gans <guru.mail@muenster.de>
* Import of data from a standard container in FListBox
is now possible
* The new "listbox" example shows the handling with
standard containers
2017-04-17 Markus Gans <guru.mail@muenster.de>
* Speed up FString::setNumber() by using a decimal
string lookup table
* FString allocates no new memory if the size sufficient
* FString allocates no new memory if the size in sufficient
2017-04-15 Markus Gans <guru.mail@muenster.de>
* Fix unsigned integer underflow in FString::_insert()
