We create an instance of our ColorNameForm as a modal dialog (third argument is TRUE). We then call its <tt>setColors()</tt> function to set the colors in the <tt>m_colors</tt> map (so that the <tt>validate()</tt> function will work correctly). We set its colorLabel's pixmap to the pixmap we've just created, i.e. to a rectangle in the user's chosen color.</p> <p>We execute (<tt>exec()</tt>) the dialog. If the user clicks OK (and the color name they've entered is valid), the call will return a true value. In this case we retrieve the name they've entered from the line edit and create a new entry in the <tt>m_colors</tt> map using the name the user has given and the color they chose.</p> <p>At this point we could simply mark the views "dirty" and call repopulate. Instead we'll add the new color to each view directly and save the overhead of a full update (which might be considerable if we have thousands of colors).</p> |
