Well, as I said a few days back, I started on writing a small concept-browser.
First run at it was using TEmbbededWB from bsalsa. IE-based obviously (6.0 in my case). I ran the test project switching tabs and the applications memory kept raising and raising … ok, so we know IE sucks but this is ridiculous.
Then, I rememberd a mozilla project long ago (mozdev) but it seems they’ve gone dead for the past 5 years so … google-ing brought me to : http://www.iol.ie/~locka/mozilla/control.htm
Now, there’s an IEPatch application there that supposidly converts it from using IE to using mozilla. Take it from me, at least with tembeddedwb, it doesn’t work. It will crash like crazy.
Now, after getting everything to work and removing the tembeddedwb stuff (including address bar) and rewriting the test project to suit the new control, things work fine. Well, almost fine because neither TWebBrowser nor TMozillaBrowser support changing the user agent (other than in the navigate method, but once you click on a link in the page, bye-bye). Aside from that, I started doing the memory test. AAAAAAnd it still leaks. Not as ugly as IE but still, about 1 MB per page load.
Ok, so this still suck.
Now, let’s find alternatives. D-Gecko on sourceforge.. dead for 2 years, no release. TGeckoBrowser on sourceforge (based on d-gecko). dead for a year, one release. Has compilation issues (mainly caused by code used for debug, not ansi compatible (in D7)). After that’s fixed, it will compile and install in the IDE.
then, for whatever reason, they inlcuded the FastMM_FullDebugMode.dll in the project. Uhm … I’m pretty sure that somehow breaks the license of fastmm but that’s another story. The main issue is: did you people never heard of conditional defines?
Loading the first sample app: ChromeWin complains of not being able to find a unit referenced. duuh, improper path on the included pas file. It’s actually in the parent directory. Once that is fixed, an AV is thrown when opening the form.
Well, so much for today.
Conclusion: it all sucks and it’s back to IE. Or the mozilla activex control. at least they’re compatible and if the mozzila activex is less memory leaky than ie, then I’ll stick with it. And maybe fix the leaks too.
