[SOLVED] How to force a tableView to only display and accept hex numbers?

lhb007

I have a tableView in my GUI design. I'd like to use tableView for presenting 32-bit hexadecimal numbers only. How can I force my tableView to only display and accept hex numbers?

Thanks

Hi,

You need to create a QStyledItemDelegate, overload the createEditor function and return a QLineEdit with e.g. a mask or a QRegExpValidator.

Hope it helps

Hi SGaist,

Thanks for your feedback. I have been able to display hex numbers in my tableView following your suggestion.

However, I still have the following issues with entering data to my tableView:

When I enter values equal or above 80000000 to my tableView cell, it displays 8 letter F's in front of the 80000000 (i.e. displays FFFFFFFF80000000).
I set @ editor->setInputMask("HHHHHHHH"); @ and I need to type 8 characters before return key works. How can I fix this restriction and be able to type any number of characters up to 8 and press the return key.

Then go for QRegExpValidator with something like

@[A-F0-8]{0,8}@

Or if you are on Qt 5, QRegularExpression

I have figured out the root cause to isseu #1. I used type "int" instead of "qulonglong" in one place in my code.

When I used QRegExpValidator and [A-Fa-f0-9]{0,8} as you suggested and removed editor->setInputMask("HHHHHHHH"); my second issue was resolved.

Thanks for your suggestion.
