Bassix + webkit + glade = micro browser

[bigbass]

Hello

I wanted a gtk3 glade with webkit example
that compiles using BaCon

I used bassix macros and several hacks
because I wanted that there was a way to modify the code visually
and easily that's why I used glade
it takes some time to get used to glade a lot of options !



now modifying the code would be much easier
and the bulk of the code and settings stay in the glade file


I was able to get it to resize too!

P.S I liked how vovchik used a combobox
for the link list so I did it in glade
looks cleaner compared to buttons

Dear Joe,

Thanks. It works! To get rid of the glade, though, we could study the glade xml and figure out where it places the vbox and hbox bits. I used this: glade2c, and am looking at the c code it generated.

With kind regards,
vovchik

hello vovchik


thanks for posting the converter glade2c
even though it doesn't produce any code that compiles (as of yet)
it is useful to some degree producing some c code to read

with a bit of hacking we could make it work(compile) maybe
(or you got it working as is ? )
another thing is web kit is not part of the database
if not too much work it could be added

all of that aside if you only want the code for the boxes
the code is there in c

Thanks
I will look at if there is some working example code
that compiles

I used the 0.0.3 version will check the others too

Dear Joe,

I know it doesn't do the webkit things - but it is still useful for getting the other widgets translated from xml into in normal c. In the meaintime, here is the old version of the bassix browser, this time with a working mailto bit.

With kind regards,
vovchik

Hello vovchik

Thanks working nicely
Its good that you worked on the load time
That can be used for many things one comes to mind

if the page takes too long break out give a warning
to try again or check your internet connection
and load an alternative url

Joe

[vovchik]

Dear Joe,

Here is the latest. I added a little graphics touch to the top, where the widgets are, just because it looks nice...

With kind regards,
vovchik

Hello vovchik

Thanks for your fine tuning


this link adds the progress differently
using a signal and the progress bar (no timeouts)
refresh and site load cancel for those sticking sites
or slow loading ones

P.S I know glade is not popular here
but we still need some examples for gtk3 with webkit
and when we need to do more a complete app
glade is much easier
to edit and see the changes
and can be fun to test ideas quickly!
and if anyone wants to start out fresh
its much easier with working demo
that compiles using the bacon compiler

Dear Joe,

Thanks. I looked at the pulsebar output, and we are never reaching a value of 1.0 for some reason, meaning full page loaded. I will have to look at the code there. I remember we once did a function that procesed a glade file that was placed inside a string variable. That is one way of keeping the the source self-contained - and we could have a switch (e.g. -d) to dump the glade file and the complete source (SOURCE$) to disk for editing/updating. I am just thinking out loud...

With kind regards,
vovchik

Hello vovchik

waiting for a 1.0 or 100
can cause extra loops
that gets the "estimated load value"
and may load faster than 100
I did try a few other ways and they
all added extra delay loops
in loading could force a 100 there if needed
but it may load sooner which is good
I see your point you would expect a full or 100 there
using the signal it has no timing issues


I was a bit hasty in my thoughts about the c code generator
I tried again today and now understand why
nothing would compile the glade2c was written
some time before gtk 2.12 that was before 2007
so after updating old code to gtk3 standards
and writing callbacks and the missing gtk code structure
I got a c code version to compile if I hadn't written
the code first and knew what it was supposed to do
that would be very difficult to port for a large program

maybe we could edit the source code and update it to gtk3
but that's still lot of work thinking...


and glade is for larger apps
in the other non glade thread of bassix
we can manually do a lot too with the fixed placement
and glade is super easy with the fixed grid also
a long time ago glade was embedded in the bacon app
which just only made it more difficult to edit the code
later and no real performance gains
development time vs having two files
both ways work which is good
I will still work using non glade also
its just an option and I feel it is more transparent
in the long run

[bigbass]

Hello vovchik

fixed the progress bar

it was really easy when I looked at it fresh again
and is correct this time

IF loadProgress == 100.0 THEN
PRINT "DONE"
PROGRESS_SET(PROG1,1)

Hello vovchik

before I said I ported my own glade / bacon version
to gtk3 (without webkit) but is an exact copy

here it is in just c code
not for everyone but just in case
its needed it now compiles clean for gtk3
and you can see all that was added

P.S it was much easier to do in glade

Dear Joe,

I like the c barebones version, since it shows the widgets we need for the gui in order to do a bassix-style version easily. Thanks.

With kind regards,
vovchik

[vovchik]

Dear Joe,

I have had some success, but still experimenting. We have to use some of this stuff, I think:

features

attributes

I have attached a little test. There is a runtime waring about casting, but we will figure that out...

UPDATED: Had some success with expand and hexpand properties. Changes in archive.

UPDATED: Added HOME and REFRESH buttons. They don't do anything yet.

UPDATED: HOME and REFRESH buttons now working.

With kind regards,
vovchik

Hello vovchik


had to replace the timeouts and use signals
for the rpi3 in the SPINNER_CB

everything else is the same with no other changes
I used ''' 3 comments were I commented out parts
so its easy to locate

let me know how it goes on the rpi4 please

Dear Joe,

Your mods are working perfectly on Mint and Pi4. I added a stop button to your latest code, and it seems to be working, too.

With kind regards,
vovchik

UPDATE: I also added a convenient expand button that does a zoom and maximizes the screen in one go. And I made nearly all the buttoms svg images for now, just for the sake of code consistency.
