@Lasith
Your problems:

You only once call the returning function of the index, and in the designer. (In fact, when ui->name text changes, the function should be called every time.)

@Lasith said in Getting QStringList text to line edit based on a string inserted on another line edit:

QString index;
Name=ui->name->text();
for(int i=0;i<names.size();i++)
{
if(names[i]==Name){
index=i;
}

You want the string but in your cycle the 'i' of the integer. Why do not you pay attention to this(index = i)? Try compile the app? If yes, the compiler would inform you about it.

From your profile it seems that you are using Qt too several months. But it does not seem to be at all.

Do not try to conquer the peak, learn to walk first.

@Lasith
No, in this case use QSignalMapper.

Store a QStringList in QSettings and pass it to a QStringListModel and then to the completer, maybe

@J.Hilk Thanx mate :) I had been too complex

Hi,

Your code won't work, your QSqlDatabase object is invalid.

Please take the time to look at the code example in QSqlDatabase's documentation as well as the example provided.

It' also discouraged to store database object like that locally. QSqlDatabase allows for easy connection handling without the need for these local copies.

Thank you @jsulm, I thought I read the documentation through, but apparently not. Also, I'm not calling QFrame. I saw the link I posted and used it as more of a guideline to create an IP Editor for my needs. Thank you for your help :)

I am going to mark this topic as Solved. I used a lot of the methodologies from this topic. I used 4 lineedits because I'm building a plugin and I want the user to be able to enter each input mask individually.

Try this , where you create ur control "dynamically"

QLineEdit * m_edit=new QLineEdit(this); m_edit->setStyleSheet(":focus{background:white}"); /*this should set the stylesheet*/

QLineEdit{ background-color:rgb(202, 255, 227);
border: 2px solid gray;
border-radius: 10px;
padding: 0 8px;
selection-background-color: darkgray;
font-size: 16px;}
QLineEdit:focus { background-color:rgb(192, 192, 255);}

Try to add this to your lineedit in the Designer.

@SGaist
Thank You so much ,
My problem solved! :)

Sounds pretty crazy...

@kshegunov
Allright, thanks for the help.

Hi,

Just a quick note, if your widget on stack (i.e. leDimWidth) gets a parent, you'll have a double delete problem since it will get destroyed when the parent is and again when your Stacker object gets destroyed.

Hi
look at this sample
http://www.java2s.com/Code/Cpp/Qt/Calculatorwithpushbuttons.htm
Shows how to hook up buttons etc. (its numeric keypad)

you can change it to use
QApplication::focusWidget () const

to input to whatever LineEdit that is selected.

might be slightly more compact to use the fill method. :)
