QTableWidget problem

[MarkoSan]

Hi to all!

I need to develop an subclassed table widget, which will look something like that:

To copy to clipboard, switch view to plain text mode 

The point is that every row consists of two lines, the upper one will hold merchandize name (solo column) and the lower one will consists of following fields in order:

• price/merchandize unit (eur formatted, including euro sign
• number of merchandize unit (formatted with leading 0)
• price/unit*number of merchandize units (eur formatted, including euro sign)
• at the end there will be total field

Does someone has any idea how to achieve that?!

Have you already tried anything?

[MarkoSan]

No, I need a few hints how to make two lines in a cell. Then I will begin.

[wysota]

Add a newline character to the string displayed.

[MarkoSan]

Ok, I am not total idiot. I need a cell, which is constructed from:

• upper string line
• and lower line, which is constructed from
  • price/unit string line and eur icon - left formatted
  • quantity string line (with leading zeros)
  • price/unit*quantity string line and eur icon - right formatted

I cannot solve this with newline character.

Well, why cant u have the brand name as column ? why need it as row ??

I am not sure of this will work... but hers my idea..
U can use delegates to have each cell as a widget. This widget has two rows... first the name, second the pprice, quantity etc.

hope it helps

I am limited with table's width, it is critical to minimize table's width because the neighbour widget must take the largest size possible because of data representation.

So, what prevents you from using multiple columns? You'll get nice alignment out of the box. Besides, I'd use tree view instead of table view.

Tree view is clumsy for touch screen user interaction. I've tried it before and because of fu... users I had to recode tree view into representation I want to do now in Qt. The same solution worked in Clarion for Windows.

You can create a layout on a widget wich has the strings that you said and icons and then set this widget as a cell widget. Though it can be slow...

The other way is to implement a delegate and draw your cell there

So. thanks for guideline, I will get to read docs about delegates ASAP.

[MarkoSan]

Well, now I have developec merchandize order class. What do I need to do to get the requested form in delegate? Reimplement the paintEvent()?? Or what?

[MarkoSan]

Well, I am slowly managing to get somewhere with my problem. Now, how do I translate the table cell (which has QString, qreal, qint16 and another qreal) from the first post into QVariant type? And how do I transfrom this cell into single QString?
