• Cross-browser method for hiding page elements until all content is loaded to prevent layout from appearing broken during load?

  - by Ryan

  I have an issue where due to some elements loading faster than others, the page looks broken for a few seconds at the start. An example is the CSS Pie behavior that allows me to do curved corners in IE, it appears before it becomes curved which looks bad. What would be ideal would be it somehow knowing when everything is loaded and then appear all at once, possibly including some kind of elegant visual way of not making the user feel impatient... any ideas or common tricks for doing this?

• How do I create an empty Django formset using modelformset_factory?

  - by nbolton

  I'm creating a formset, but it seems to populate it with all of the existing data in the table for that object. I can't figure out how to start with a blank formset; the only way seems to be to delete all of the data from the table, but clearly this isn't an option. I will post code if necessary (but there's lots of it, so knowing what is relevant is tricky).

• android - How to draw only the sprite from an image on the canvas

  - by user1320494

  this is the first time for me here, so I hope I'm doing this right :) My question is the following: how do I draw the sprite from an image on the canvas, so that I don't get the entire (squared) image to show, but only the parts of the image I want (= the sprite). For example, I have an image of a robot on a white background and I only want to see the robot, and not the white background. I hope someone here can help me with this problem, because it's giving me headaches of not knowing how to do it :P
