PB 5.20 B2 GTK3 subsystem for Linux

[uwekel]

Hi,

i cannot see anything of GTK3. When i compile and run on linux, i only get the GTK2 widgets (best compared by the SpinGadget which has been deeply re-designed). What has to be done to get the GTK3 widgets?

Best regards
Uwe

Gadget.pb from example dir with and without subsystem gtk3

you need to specify "gtk3" in the subsystem field of the compiler options.

The Gtk3 SpinButton normally renders like this (with +/-buttons inside):

The PB SpinGadget looks like always. Isn't it inherited from GtkSpinButton?

[Fred]

You are right, this one is custom made, probably because GtkSpinButton didn't exists in old version of GTK

Compiling PB examples while adding GTK3 as subsystem results in an linker error:
...undefined reference to symbol 'XInternAtom'.
Library libX11.so.6 is on the system as well...

BTW same files with GTK2 compile as expected.

Linux OS: Manjaro XFCE

ts-soft,
I tried to add the missing lib to the linker (compiler options) but it didn't work.

As always: you have the answerrs.

Thank you.

[ts-soft]

you can edit the ld.so.conf as root:
/etc/ld.so.conf

Add the path to missing lib like
/usr/lib
or
/usr/lib64
or
/usr/lib32

than in terminal as root
ldconfig

or
sudo ldconfig

With GTK2 the WebBrowser example works as expected, the gadgets are resized accordingly when the main window is resized.
With GTK3 the WebBrowser main window resizes itself (right after the start); it's bigger than the desktp size.
It's also unresponsive...

Are the examples not tested before release of a beta?
