[URGENT] Need some help with QT creator

[mahindar_275]

Hi friends,

I was trying to make a simple program. I haven't wrote any code
I just added three text fields and a button... When i press the button the numbers in textfield1 and textfield2 should get added a displayed in textfield3.

I tried this
onClicked: textfield3 = textfield1+textfield2
but it didn't work

I think they should be converted into integer and then should be added

Any one suggest me how to do that..
Sorry for my bad English

That will treat the numeric value entered in the text field as string only. So if you entered '2' in text field 1 & '3' in text field 2 then textfield1+textfield2 would result in '23'.

To make this work you can utilize ParseInt method as below:


onClicked: textfield3.text = parseInt(textfield1.text) + parseInt(textfield2.text)

See if this works.

Do you mean that you always want to keep the focus on the text field, if yes then you can keep the focus as always true for TextField:

focus: true
