I'm begining developing the Quicklook for windows. Here it's my ideas for design, for available controls for plugins' developers.
On the picture (attach was painted by me
) you can find following controls/places:1. Image control - you will be able to add any picture from file's path/HICON/memory/may something else.
2. Text control - just setup text's size, style, color, alignments and etc.
3. The client area, where your (plugin's) controls will have a place.
4. Command button - just a button, I think it will be enough (for the first time) only change its text.
5. Radio/Check boxes - they are the same, but only one thing, radio controls that only one button can be checked.
6. Track bar - may create only two styles (large/small) or may make possible to control height, color of the background, size, gradient colors of the track button.
7. There are buttons you will be able to add your own buttons (but it would be another API, not like for client area, I will think about later).
Plugin - it's a simple .dll file (may rename extension). You write a plugin using Quicklook's API.
I'm going to implement following:
1. Controls, also create Video Player, Coverflow, Text viewer/editor...
2. You won't have to know anything about DirectShow, Gdiplus and so on, you will just set your properties for controls and simply run them.
3. Every control has its own ID (DWORD). Using this ID, you can get/set all properties using the same API. You just prepare a special structure and install neccessery flags (for properties) and call API.
After all, when the base will be written, I think only then we can create a new type of control - container. What does it mean ? You can create container (on client area), then receive its handle (HWND), and place your child windows there.
Here it's only what I know/think about for now.
If somebody wants to join me, just send me a private message or write to ICQ 240605815.
Thanks. Vladimir.
