Hi,<br><br>I think we discussed (Aaron proposed the idea) about having a method using which we could ask a wallpaper plugin if it supports an Image-based wallpaper. If it says true, we just ask it to set the specified image, and if it doesn't, then we change the plugin to Image.<br>
<br>What do you guys think?<br><br>-- <br><div><br></div>Shantanu Tushar (UTC +0530)<br><a href="http://www.shantanutushar.com/" target="_blank">http://www.shantanutushar.com</a><br><br><br><div class="gmail_quote">On Thu, Jan 27, 2011 at 12:06 AM, todd rme <span dir="ltr"><<a href="mailto:toddrme2178@gmail.com">toddrme2178@gmail.com</a>></span> wrote:<br>

<br></blockquote></div><br><br>I see one issue with this approach: it hard-codes how to deal with different plugins. What happens to the weather wallpaper? What happens to wallpaper clock or day/night wallpaper? What if someone writes their own version of the slideshow plugin? Is someone going to rewrite this every time a new plugin is developed?<br>
<br>Might it be a better approach to have some general API for setting images to a wallpaper? The plugin would set up its own method of dealing with the pictures sent to it (which could include ignoring it). The the default plugin and virus plugin would just set the image, the slideshow plugin would add it to the list, the weather plugin would set it to the current weather condition, the day/night and clock plugins would set it to the current time.<br>
<br>As a fall-back, if the plugin does not support the API, plasma would change to the normal wallpaper image and use the image there. So plugins that don't use images, like marble and mandelbrot, could just not implement that API, in which case selecting an image would change to the default plugin and then set the image to that.<br>
<br>This also has the benefit that other widgets would also be able to hook into this and change the wallpaper without much work and without worrying about what plugin is being used.<br><font color="#888888"><br>-Todd<br>

Patch works for all cases. Suppose current wallpaper is virus. If User
has images in Picture frame and if he likes to set the Picture frame<br>Image
as wallpaper image. He can do so. "set wallpaper Image" sets the
current image as wallpaper image and Wallpaper Plugin will be set to
Image.<br clear="all"><br></div></div></div></div><font color="#888888">-- <br><a href="http://www.sinny.in" target="_blank">http://www.sinny.in</a><br>

<br></div></blockquote></div><br>Why should the plugin be set to image? I picked the virus plugin as an example because it uses an image as a wallpaper, but then manipulates the image. So if someone is using the virus wallpaper, and they select "set wallpaper Image", I think the expected behavior would be that the virus plugin starts using that image, not to change the plugin entirely. Similarly, if someone is using the weather wallpaper, and they select "set wallpaper Image", I think the expected behavior would be to use the image for the current weather, not to change the plugin. The same goes for the day/night wallpaper and the wallpaper clock. These all use images in various ways. I don't think people would be expecting this option to change the plugin, rather I think they would expect it to use the image in the plugin.<br>
<br>Then you add situations I mentioned like someone making a photo montage wallpaper, which scatters a bunch of pictures over the desktop. Would you modify this function to deal with that properly, or would you erase their montage?<br>
<br>I think the only way to do this properly is to let the plugins decide for themselves how to handle pictures sent to them. If a plugin doesn't provide a way to handle pictures, only then do you resort to changing the plugin.<br>
