The API functions are similar so one can +expect the function to behave in the same way. + +Some features: + + - The buttons are highlighted a la Firefox style + - The scrolling is done for bulks of tabs (so, the scrolling is faster and better) + - The buttons area is never overdrawn by tabs (unlike many other implementations I saw) + - It is a generic control + - Currently there are 5 differnt styles - VC8, VC 71, Standard, Fancy and Firefox 2; + - Mouse middle click can be used to close tabs + - A function to add right click menu for tabs (simple as SetRightClickMenu) + - All styles has bottom style as well (they can be drawn in the bottom of screen) + - An option to hide 'X' button or navigation buttons (separately) + - Gradient coloring of the selected tabs and border + - Support for drag 'n' drop of tabs, both in the same notebook or to another notebook + - Possibility to have closing button on the active tab directly + - Support for disabled tabs + - Colours for active/inactive tabs, and captions + - Background of tab area can be painted in gradient (VC8 style only) + - Colourful tabs - a random gentle colour is generated for each new tab (very cool, VC8 style only) + + +And much more. + + +License And Version: + +FlatNotebook Is Freeware And Distributed Under The wxPython License. + +Latest Revision: Andrea Gavana @ 22 Nov 2007, 14.00 GMT + +Version
