[Konsole-devel] DCOP to DBUS migration - issues

[Robert Knight]

Hi Marian,

Thank-you for the feedback.

> Invalid number of parameters

Ah, there are two newSession() methods, one with parameters and one
without.  It seems that qdbus does not support overloading and only
allows the first to be picked based on the name.  That's pretty stupid
on Konsole's part - it can be fixed by changing the method name of one
of the instances or removing one of them.  Otherwise it might be
possible using a different command-line tool.  I'm not sure if
dbus-send supports this.

There is a 'hidden' konsoleprofile command-line tool to set per-tab
properties.  This tool echoes a "profile-property=string" message to
Konsole
preceeded by a special escape code (open konsole-profile in a text
editor to see).  You can invoke this from DBus using:

qdbus org.kde.konsole /Sessions/$sessionId
org.kde.konsole.Session.sendText "echo -e
'\033]50;colorscheme=WhiteOnBlack\a'
"

This can be used to set (almost) any profile property per-tab.
Multiple profile=value assignments can be put in the same command
separated by semi-colons.  The tab title can be set using a
combination of "LocalTabTitleFormat" and "RemoteTabTitleFormat"
properties, the tab title update will happen after a short delay.  The
font can be set using the "Font" property, eg. "font=Monospace,12"
The possible property names and values are the same as those used in
the .profile files created in ~/.kde/share/apps/konsole when you
create
profiles in the GUI.

You can set the codec using the setCodec() DBus method.  It would be
useful to have explicit methods for things like the color scheme to
make the interface easier to figure out though.

> 3) There is not a possibility to copy/clone actual profile. I have to create each from default.

Pressing the 'New' button creates a copy of the selected profile.  I
think this is not obvious enough from the UI though.

Regards,
Robert.
