linking of combox with lineEdit.

[Devoraz]

Hi. from the image. i would like to link the Combox with the lineEdit. as in i select End device 1, only the things in end device 1 would be change to whatever i type in the lineEdit. can anyone give me some example of code about doing it?

connect the singnal of combobox activated() to some slot in your dialog and play with lineedit

i know the connect part. but how about the play part?

[nish]

but how about the play part?

you have not explained very well what is the play part?

only the things in end device 1 would be change to whatever i type in the lineEdit.

what the heck anybody can understand by this?

[Devoraz]

i have attach an image what..

[nish]

why cant you rephrase your question?
do you whant to change the text in combobox to whatever u type in lineedit?


EDIT..

i still cant understat what is qTemp?

[Devoraz]

do you whant to change the text in combobox to whatever u type in lineedit?

nope. okay i roughly explain what i am doing and what i want. first for the image there is a yellow node. they will be 8 of them. so my combobox i already set it to 8 choice. from "End Device 1 to 8"

so now lets say when i select End device 1 on my combobox, and a type a certain word in the lineEdit. when i press ok. the word in the line edit will appear on the yellow node.

i still cant understat what is qTemp?

nvm just know it as printf.

do it like this..

//main
MyDialog dlg;
 
if(dlg.exe()==QDialog::Accepted)
{
  int deviceId = dlg.getDeviceId();
  QString word = dlg.getWord();
  if(!word.isEmpty())
   putWordInUse(word);
   .....
  ...
}  
 
//MyDialog
int MyDialog::getDeviceId()
{
  return combobox->currentIndex()+1;//0+1=end device 1 ,1+1..... 
}
 
int MyDialog::getWord()
{
  return lineEdit->text();
}

//main
MyDialog dlg;

if(dlg.exe()==QDialog::Accepted)
{
  int deviceId = dlg.getDeviceId();
  QString word = dlg.getWord();
  if(!word.isEmpty())
   putWordInUse(word);
   .....
  ...
}  

//MyDialog
int MyDialog::getDeviceId()
{
  return combobox->currentIndex()+1;//0+1=end device 1 ,1+1..... 
}

int MyDialog::getWord()
{
  return lineEdit->text();
}

To copy to clipboard, switch view to plain text mode 

do not forget to connect the ok button to accept() slot of QDialog
