Talk:Edje examples

Revision as of 14:40, 2 February 2009

Comments and questions are welcome

TODO: add some theory.

Questions:

• Howto deal with dynamic user interfaces, e.g: tabular data?

I have seen that there is a new part type: TABLE, maybe this can help ?

• Where can i find the api to be used in embreyo scripts ?

Functions I dig out of the edje source:

numargs();
 getarg(arg, index=0);
 setarg(arg, index=0, value);

 Float:atof(string[]);
 Float:fract(Float:value);
       round(Float:value, Float_Round_Method:method=ROUND);

 Float:log(Float:value, Float:base=10.0);
 Float:sin(Float:value, Float_Angle_Mode:mode=RADIAN);
 Float:cos(Float:value, Float_Angle_Mode:mode=RADIAN);
 Float:tan(Float:value, Float_Angle_Mode:mode=RADIAN);
 Float:abs(Float:value);

       strncat(dst[], src[], n);
       strprep(dst[], src[]);
       strnprep(dst[], src[], n);
       strcut(dst[], str[], n, n2);
       snprintf(dst[], dstn, fmt[], ...);
       strstr(str[], ndl[]);
       strchr(str[], ch[]);
       strrchr(str[], ch[]);

• Are there any default fonts, colorclasses, styles or images available?
• Is it possible to dynamically determ the source of signal when wild cards are used ?
• Is it possible to declare transparency of images?

It possible todo this with edje_editor but I didn't found attribute yet.

• Using an edje/evas program as root window (dedicated application)?

When setting the fullscreen attribute on the evas canvas the canvas will occupy the complete screen.

• Howto use gstreamer as backend of emotion ?
• What is e_dbus exactly (is it wrapper around dbus?), which services are there ?
• Is it possible to mix edje user interface with ewl elements ?
