[fpc-pascal] Re: html link extractor

It is a little heavy handed to create and free two classes just to do a simple task like get some urls from a web page. Some day I'll make a simpler even lighter version of that parser for quick and dirty usage, but still keep the old one maybe.

[fpc-pascal] How to call a pascal function from c?
Hi Everyone, I have code written in pascal and I'd like to call from C. Any doc or link or example to see how? thank you, best regards Jose Pascual ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
[fpc-pascal] fpcanvas and FloodFill()
Hi, Still trying to implement fpcanvas as the bases classed for fpGUI. What is the function of...? TFPCustomCanvas = class procedure FloodFill (x,y:integer); ... How is it supposed to differ from Canvas.Clear() and Canvas.Rectangle() which can both handle filling of a rectangle?

It fills the canvas (in all directions) till it encounters a different color which differs from the starting color. You can use this to fill irregular shapes.

The hard bit (without looking at any code) will be the rules when to paint. Am I understanding FloodFill() correctly. For example: If we have a Canvas with shapes painted on it. The inside of a rectangle might have the same background color as the canvas, but we don't want to paint inside the rectangle as it is a closed shape. Then we might have a another shape with a outline, but the shape isn't closed (end points of polygon doesn't meet up), so we still need to paint inside it. This is going to be fun. I'll have a look at those units you mentioned. So far I have implement about 70% of TFPCustomCanvas in my new fpGUI framework. I've also completed Canvas.Pen, Canvas.Brush and Canvas.Font support. All under X11 only, but now that I know what to do, GDI should hopefully go quicker.
