 (wxWidets originated in Edinburgh and therefore uses some quaint spellings going back to Anglo-Norman times.) At the beginning we read the current color into the variable '''OldColour'''. In the next line, we call the '''wxGetColourFromUser''' function which opens a dialog where the user can choose a colour.

+At the end, we set the new colour by using the '''SetForegroundColour''' function. Refresh is needed to change colour after setting it.
 If, however, you try to compile this code, you will get an error message telling you that  wxGetColourFromUser() is an unknown function. Since we put it in manually, we must also put in manually its header. So open the Tutorial_6Main.h file and add #include <wx/colordlg.h>.

 The last thing we will do in this tutorial is to change the color of some item. As in the case of fonts we will change the label on the left side of the '''Change''' button. Since we will use the standard event of this button, we can add an event handler by double-clicking on it. And here's the code:
