Hi Jeremy, in your valgrind there are still these massive DilloImage related leaks. Can you please make sure that you are running the latest version of my img_ref patch (attached)? I add added prints to a_Image_new() and Image_free() and recorded them in a logfile. With the patch the numbers seem to match fine here. Cheers, Johannes

This has to be asked in fltk general before discarding it. If there's no way, a right-click button may be of help. This is left-click on RCB and the next left-click will be processed as a right click. The idea is to try to reuse the UI as much as possible, and to just code the necessary hooks for it. Please contact Andreas K., he may have good ideas for handheld related issues. -- Cheers Jorge.-

There is a module for gtk2 (libgtkstylus.so) that simulates a right click when the user holds the left mouse button, that works quite nicely in practice. That was actually what I wanted to implement at first. I looked through the fltk2 event handling code (most thoroughly with respect to the button widget) and I am convinced that this behavior cannot be implemented without patching fltk2 since the widgets do not call the callback when the button is pressed but only when it's released. I prototyped a solution that abuses the DRAG events to detect PUSH events, but that didn't work very well since DRAG events are only emitted when the cursor moves. Patching fltk2 to also call the callback function on PUSH events is problematic since (at least in dillo2) many callback functions do not test properly whether they are actually interested in that particular event and just assume that it must have been a RELEASE event. >> Adressed in the second patch which adds an add bookmark button to >> the main toolbar. > > What about a dillorc option to make it optional like the other > buttons? Sure thing, that would be great. It shouldn't be too hard to make the toolbar content configurable. >> * the scrollbars are unusable without a stylus >> >> A more natural way of scrolling on embedded devices with touchscreens >> is finger scrolling.

The changes are actually quite small since a similar functionality was already present, namely panning via the middle mouse button. My patch just adds a configuration option to do so with the left button and to fiddle with the event handling code (you have to pass some events to the page content or you end up with a browser with non functional links :)). Note that this is just a mockup that needs some cleanups (works only for the first tab, need to adjust the open tab functionality in uicmd, text selection works fine with a mouse but is next to impossible on the moko due to double click tolerances (at least thats what I think)). And the text selection part is not configurable at the moment, that's the most problematic part. Any thoughts on how to make dw configurable at runtime while keeping it implementation agnostic with respect to the frontend? Justus

Why not, if that's better for mobile devices and if it's configurable. Cheers, Johannes

[PATCH 0 of 3] tweaking the dillo ui for embedded devices

by 4winter＠informatik.uni-hamburg.de

Hey folks :) I've got a new toy (the Neo FreeRunner) and dillo2 runs quite nicely on that little device, but there are some problems: * there is no way to create bookmarks Adressed in the second patch which adds an add bookmark button to the main toolbar. * the scrollbars are unusable without a stylus A more natural way of scrolling on embedded devices with touchscreens is finger scrolling. A proof of concept is attached as the third patch. Acceleration would be a nice feature for big pages. * buttons on dialogs are too small Proposed solution: There is code for creating dialogs in src/dialog.cc for a_Dialog_choice5 that creates the dialog window without relying on fltks choice(). We could generalize that and use it for all dialogs. This way we could resize the buttons and stack them vertically on top of each other. What do you think? Justus ps: the first patch is a small cleanup patch. all three patches should apply cleanly independently in spite of being a patch set)
