QLineEdit set min max range?

[whitefurrows]

Hi,

sorry the late answer, but i have a long time read the doc and written code. I thing the right way is disabling widgets.

I do this to check QValidator::State:

int pos = 0; 
   QValidator::State state; 
   QList<QLineEdit *> leList= this->findChildren<QLineEdit *>(); 
   for (int i=0;i<leList.size();i++){ 
      state = leList[i]->validator()->validate(leList[i]->text(), pos); 
      if(state == QValidator::Intermediate && leList[i]->text() != ""){ 
         //disabling widgets
      } 
   }

int pos = 0; 
   QValidator::State state; 
   QList<QLineEdit *> leList= this->findChildren<QLineEdit *>(); 
   for (int i=0;i<leList.size();i++){ 
      state = leList[i]->validator()->validate(leList[i]->text(), pos); 
      if(state == QValidator::Intermediate && leList[i]->text() != ""){ 
         //disabling widgets
      } 
   }

To copy to clipboard, switch view to plain text mode 

That's worke fine, but i get a error if a QLineEdit without QValidator.

How can i check if QLineEdit Validator set, or you know a other solution?

How can i check if QLineEdit Validator set, or you know a other solution?

const QValidator * QLineEdit::validator () const
Returns a pointer to the current input validator, or 0 if no validator has been set.

So this should work:

...
QList<QLineEdit *> leList= this->findChildren<QLineEdit *>(); 
for (int i=0;i<leList.size();i++){ 
   if( leList[i]->validator() != 0 ) {
      state = leList[i]->validator()->validate(leList[i]->text(), pos); 
      ...
   }
}

...
QList<QLineEdit *> leList= this->findChildren<QLineEdit *>(); 
for (int i=0;i<leList.size();i++){ 
   if( leList[i]->validator() != 0 ) {
      state = leList[i]->validator()->validate(leList[i]->text(), pos); 
      ...
   }
}
