If I have understood you correctly, you want Dw_page_draw_line to determine the positions of the floats. This will make calls to a_Dw_widget_size_allocate (for embedded child widgets) neccessary, which does change the state, at least of the widget tree. You really should put your code is Dw_page_size_request and Dw_page_size_allocate. Please read the documentations, both of Gtk+ (which is quite similar to Dw), and Dw. Especially, try to understand the implementation of "incremential resizing" (when something is unclear, I'll answer questions about it). > > - Floats may exceed the allocation of the DwPage, so they may not be > > a child widget, instead, an interaction between two DwPage's is > > necessary. > > When does a float exceed the allocation of the DwPage? > Is there a new DwPage for new paragarphs? Currently, nested DwPage's are used for: 1. any blocks with a margin different from zero (<blockqoute>, <ul> and some others): DwPage had originally the possibility to indent single blocks, but when I one redesigned DwPage (to fix a CPU lock), I decided to simplify it by removing this feature. 2. Any <li>, since this makes dealing width the hanging bullet/number much easier.

Child widgets must *always* size_allocated, also when they are not visible. Sebastain

Re: [Dillo-dev] if dillo is embeddable, what would it take to embed it in itself so that dillo can do frames?

The "dillo embedded in istelf"-idea crossed my mind, too. If you do that you spawn unnecessary processes. Also, you have to be really careful about tracking history (the back button still needs to work somehow). Also, the target tag needs to work - that would probably be only a minor problem. Those were just some ideas ... I may be wrong. But right now I hack around to put a_Interface_browser_window_new into an existing window. But, on the one hand, a_Interface_browser_window_new probably needs to be modified or cloned and on the other hand I know too little GTK I'm afraid :-) Just if anybody cares :-) ..... If I was certain I could get somewhere, I would have added myself into the bug tracking engine.

if dillo is embeddable, what would it take to embed it in itself so that dillo can do frames?

by John L.Utz III

Now, i happen to hate frames, and prefer to do the 'fake frames in tables' thang (which other people hate :-) ) , but their are a lot of misguided webdevs out there who have chosen to implement their site with frames, and i actually need to get information from them every now and then. For instance, going to this one in dillo is a pathetic folly :-) : http://www5.metrokc.gov/webmaps/parcelviewer/Viewer/KingCounty/viewer.asp so if dillo can be embedded in sylpheed, why cant dillo be embedded in dillo? tnx! johnu

Changing font_factor dynamically

by Gregor Hoffleit

[Please pardon me if this is the wrong forum for such feature requests.] I'm using dillo with familiar on my iPAQ. One thing I'm regularly missing is a possibility to change the font_factor setting dynamically: For the iPAQ's small display (240x320 minus a few decorations), a single font_factor just can't fit for all different pages: For some pages, I'm glad with font_factor=0.5, with others, font_factor=0.6 is readable. I guess it's a major effort to implement a dynamical switch of the font_factor (e.g. using a pull-down menu), but I would be glad if you could discuss this feature request. Thanks for your efforts, Gregor Hoffleit

-l switch not working if <base href="..."> is given

by Melvin Hadasht

Hi, The -l switch is meant to disallow retrieving external resources. This works fine unless the html file contains a <base href="something"> tag: in that case, the external resources are retrieved. To check this, I made a test case with an excerpt of the google search page. The attached html files just display the google logo in a table. These two attached html files differ in that "index.html" has the <base> tag commented out, making it non functional, whereas in "index-base.html" it is taken into account. To test this bug, save both html files in a directory. Then create there a subdirectory called ./images where you save the logo.gif. (This is meant for index.html where the missing <base> defaults it to the current directory. In that case, dillo index.html will show the logo, as expected). Then run dillo with the -l switch on the two files: dillo -l index.html index-base.html. The index-base.html will show the logo retrieved from http://www.google.com/intl/en/. The expected behaviour is to not retrieve it. I'll try to look into this bug this weekend, but I'm not so familiar with dillo's internals, so do not expect a miracle. I nearly forgot, this is the released dillo 0.7.0. Cheers. -- Melvin Hadasht
