Hi, Edje people (Cedric, Raster, mainly).
When centering two or more parts on a broader layout, with no use of
offsets (think scalable interfaces), it's of great use to have these
sub-parts bundled in a subgroup, which can easily be
centered. However, Edje has a bug when calculating the minimum size of
a (sub) group of this kind:
collections {
group {
name: "group";
parts {
part {
name: "bg";
type: RECT;
mouse_events: 0;
description {
state: "default" 0.0;
color: 0 255 0 100;
}
}
part {
name: "padding";
type: RECT;
mouse_events: 0;
description {
state: "default" 0.0;
min: 50 0;
max: 50 -1;
align: 0 0.5;
rel1 {
relative: 0 0;
}
rel2 {
relative: 0 1;
}
}
}
part {
name: "elm.text";
type: TEXT;
mouse_events: 0;
description {
state: "default" 0.0;
align: 0 0.5;
rel1 {
to_x: "padding";
relative: 1 0;
}
rel2 {
to_x: "padding";
relative: 1 1;
}
text {
min: 1 0;
text: "blablabla";
font: "Sans";
size: "30";
}
}
}
}
}
}
Naturally, the parent group of that one would look like
part {
name: "broader_group";
type: GROUP;
mouse_events: 0;
source: "subgroup";
scale: 1;
description {
state: "default" 0.0;
min: SOURCE;
rel1.relative: 0.5 0;
rel2.relative: 0.5 1;
}
}
thus, enforcing its minimum size calculation via min: SOURCE.
Edje, however, miscalculates the horizontal size of "group". Try
running 'edje_player -g=group FILE_WITH_GROUP_COMPILED.edj' on the 1st
(inner group). Then, start resizing edje_player's window horizontally,
make it smaller. You'll see that it goes past 50 pixels from the
string's ending, exactly the size of the white rectangle in X! Edje
simply overlaps those minimum sizes together (rectangle's explicit
50px min + text's implicit min: *1* 0), instead of adding them, to
generate a minimum size to the group!
Can anyone help here?
Thanks.
