Revision 4. </p> <p>Frame with linear gradient using PIL. </p> <p>It's also possible to make the same trick using tkinter PhotoImage.</p> <p><a href="http://stackoverflow.com/questions/10417524/why-is-photoimage-put-slow" rel="nofollow">http://stackoverflow.com/questions/10417524/why-is-photoimage-put-slow</a></p> <p>But PIL is more efficient:</p> <p><a href="https://groups.google.com/forum/#%21topic/comp.lang.python/nQ6YO-dTz10" rel="nofollow">https://groups.google.com/forum/#!topic/comp.lang.python/nQ6YO-dTz10</a></p> <p>Possible values for <strong>orient</strong> are: <em>VERTICAL</em>, <em>HORIZONTAL</em>. If <strong>orient</strong> is "vertical", then width is mandatory. If <strong>orient</strong> is "horizontal", then height is mandatory. If <strong>steps</strong> is <em>None</em>, then the gradient is composed of adjacent lines.</p> <p>One possible practical application of gradient frames are tool bars. Gradient guives a visual clue of when an area starts and when an area finish. </p>

<p style="color: grey"> Python recipe 577409 by <a href="/recipes/users/4174115/">Sunjay Varma</a> (<a href="/recipes/tags/canvas/">canvas</a>, <a href="/recipes/tags/rectangle/">rectangle</a>, <a href="/recipes/tags/selection/">selection</a>, <a href="/recipes/tags/tkinter/">tkinter</a>). </p> <p>A simple, yet effective rectangle selection box. :)</p> <p>Works with a tkinter canvas! Just add the class and set it up like in the example code. The cross heir was my own touch, the RectTracker only draws a box.</p> <p>Have fun! And please don't just vote down, post what you don't like if you don't like it.</p>
