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 4 differnt styles - VC8, VC 71, Standard and Fancy. +- 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. + + +Usage: + +The following example shows a simple implementation that uses FlatNotebook inside +a very simple frame:: + + import wx + import wx.lib.flatnotebook as FNB + + class MyFrame(wx.Frame): + +
