    Default How to fill the blocks of the Grid one by one?

    Hi all

    Working on Qt4.2 on my Intel MAC.

    I had made a grid of 16x16 on a widget,in which there are 256 blocks,
    I also used a QPushButton with this.

    Now what I wanted to do is this when I click on the button , the first block of the grid should be filled with the colour ,

    when I again clicked on the button the second block of the grid should be filled with the colour, and so on;

    i.e on every click of the button the blocks of the grid should be filled with the colour.

    If anybody understand my problem then Pls Help

    Thanx
    Always Believe in Urself

    What do you mean with "grid", a grid layout?
    you mean you have 256 buttons in agrid layou on a widget?

    You didn't explain what the problem is, only what you want to do.

    If the problem is that you don't know how to do it then:
    create a member variable to store the current block number.
    Create a slot, and connected it to the clicked() signal of the button.
    In the slot, fill the current block with color, and increment the block number.
    Done.

    Do you write clean code? - if you are TDD'ing then maybe, if not, your not writing clean code.
