Hi Alan, Thanks for the reply. I apologize, the QTJ in my email is a typo, it was meant to be QT followed by a smiley ---> : ) but some text renderers turn the colon-parenthesis sequence into a J for some reason. The same thing happens on my android email client...
Anyhow, I am glad you replied because I do have a decision to make regarding our application. It is currently written in fltk and I'd like to embed some plots into it. But the gui portion is not large so it is a balance between writing the fltk driver and switching our gui into qt and using that driver. I have to check with the team before I make the call. I also was wondering if the mem driver might work as an initial proof of concept for us. It seems using that driver we can obtain an image that can then be rendered by any gui toolkit that can handle displaying pictures. Is this correct? I am basing this only on browsing through the code because I could not find examples besides the one written in python. I did look through the qt driver thinking the same thing, that this would be the template we could use to write the fltk driver. It seems the driver is just an interface that matches Plplot's api with the GUI toolkit's so that input or expose events in the gui can be sent and handled by PlPlot and then drawing events are passed to the gui along with the data in order to manipulate the image. Am I close on this? We do have other applications already using fltk and although I am not necessarily a fan of it, I don't see us switching any time soon. So with time it might be possible for myself or my team to write a driver for it. No promises but if we do we'll let you know. -Marco -----Original Message----- From: Alan W.

If that is QuickTime for Java (usually referred to as QTJ), then we don't support it. I checked back over our mailing list messages, and there were a few mentions of fltk, but nothing serious. Therefore, if you wanted to develop a PLplot device driver based on fltk, I am virtually positive you would not be duplicating anyone else's effort. Our current interactive devices (with device driver in parentheses) are the following: tk (tk) xwin (xwin) wxwidgets (wxwidgets) xcairo (cairo) qtwidget (qt) -dev tk has our most comprehensive GUI capabilities, but its big drawback is support just for the ugly Hershey fonts. A smaller drawback is it uses full X capabilities (not the limited cross-platform X) so it doesn't work on Windows. The rest of our drivers have limited GUI capabilities, but that is something that should be straightforward to fix if anybody was keen so I won't mention this is the summaries for the rest of our interactive devices. -dev xwin just uses Hershey fonts. It is stable and fast, but does not work on Windows. -dev wxwidgets works on all three OS platforms (Linux, Mac OS X, Windows). It does have some on-going maintenance issues although I keep hoping those will be rectified by some interested volunteer. It does have access to high-quality fonts, but the plfreetype method used is not recommended any longer since controlling the fonts used (by mentioning the font files by name) is painful and also inflexible. It should be straightforward to move to a fontconfig method of controlling the fonts, but nobody has volunteered to do this. Another issue is the plfreetype method simple renders the text in left-to-right fashion so use of wxwidgets with CTL (complex text layout) languages does not work. -dev xcairo and -dev qtwidgets are well-maintained modern interactive device drivers for PLplot which can render CTL languages with ease in a huge variety of fonts that are easily controlled by the user. They also work on all the major OS platforms (Linux, Mac OS X, and Windows). These are the interactive GUI device drivers to use for a prototype if you are going to develop a fltk-based device driver. Alan __________________________ Alan W.
