直接使用QRegExp/QValidator，通过setValidator设置

QRegExp     regMaxPower("^(\\d{1,6})|((\\d{1,6})\.\\d{1,5})$");//最大动能       QRegExp     regWeight("^(\\d{1,3})(\.\\d{1,4})$");//重量       QRegExp     regSpeed("^(\\d{1,5})(\.\\d{1,5})$");//速度       QRegExp     regAirvolume("^(\\d{1,5})(.\\d{1,5})$");//充气体积       QRegExp     regMileage("^(\\d{1,5})(.\\d{1,5})$");  //续航里程       QValidator *validatorMaxPower=new QRegExpValidator(regMaxPower, ui.editMaxPower);       ui.editMaxPower->setValidator(validatorMaxPower);       QValidator *validatorWeight=new QRegExpValidator(regWeight, ui.editMaxPower);       ui.editEmptyWeight->setValidator(validatorWeight);       ui.editMaxWeight->setValidator(validatorWeight);       QValidator *validatorSpeed=new QRegExpValidator(regSpeed, ui.editMaxPower);       ui.editMaxspeedLevel->setValidator(validatorSpeed);       ui.editMaxspeedRaise->setValidator(validatorSpeed);       QValidator *validatorAirvolume=new QRegExpValidator(regAirvolume, ui.editMaxPower);       ui.editAirvolume->setValidator(validatorAirvolume);       QValidator *validatorMileage=new QRegExpValidator(regMileage, ui.editMaxPower);       ui.editMileage->setValidator(validatorMileage);

结果：效果不好

   QRegExp     regMaxPower("^([0]|[1-9][0-9]{0,4})(\\.\\d{1,4})?$");;//最大动能   QRegExp     regWeight("^([0]|[1-9][0-9]{0,1})(\\.\\d{1,3})?$");;//重量   QRegExp     regSpeed("^([0]|[1-9][0-9]{0,3})(\\.\\d{1,3})?$");;//速度   QRegExp     regAirvolume("^([0]|[1-9][0-9]{0,4})(\\.\\d{1,3})?$");;//充气体积   QRegExp     regMileage("^([0]|[1-9][0-9]{0,4})(\\.\\d{1,4})?$");;  //续航里程   QValidator *validatorMaxPower=new QRegExpValidator(regMaxPower, ui.editMaxPower);   ui.editMaxPower->setValidator(validatorMaxPower);   QValidator *validatorWeight=new QRegExpValidator(regWeight, ui.editMaxPower);   ui.editEmptyWeight->setValidator(validatorWeight);   ui.editMaxWeight->setValidator(validatorWeight);   QValidator *validatorSpeed=new QRegExpValidator(regSpeed, ui.editMaxPower);   ui.editMaxspeedLevel->setValidator(validatorSpeed);   ui.editMaxspeedRaise->setValidator(validatorSpeed);   QValidator *validatorAirvolume=new QRegExpValidator(regAirvolume, ui.editMaxPower);   ui.editAirvolume->setValidator(validatorAirvolume);   QValidator *validatorMileage=new QRegExpValidator(regMileage, ui.editMaxPower);   ui.editMileage->setValidator(validatorMileage);
