In 3.10 version, Qt4 converted automatically a number with ',' as decimal separator to the right format. <br/> In 4.2, Qt5 fails to convert 4,56 to 4.56, so the value stays unchanged.<br/> The purpose of this issue is to display the values in TYDimensionDialog according to the locale of the system.<br/> In the previous example, 4,00 will be displayed, and the user will have to enter 4,56 to modify the value.<br/>
