TODO
====
* zoom
* BUG: show nodes labels does not show old nodes labels
reproduce: do not show labels, add edges, show label, add edges
* BUG: sometimes when you add nodes during layouting, the graph is broken
a new edge attaches to the wrong new vertice
it seems to be always the same node numbers that gets this wrong edge
* BUG: vertices / vertices text fight for being on top. use evas layers ?
add 500 edges to reproduce, and watch the nodes
* speed: evas_object_rectangles
04:40 <@raster> they add clipoouts
04:41 <@raster> make them just a bit translucent
04:41 <@raster> and it'll be faster
* find a better storage type for vertices
quick access O(1) -> table
possibility to foreach and remove at the same time
* possible future API: no edges no vertices for the user
struct Egraph_Vertice {
const char *name;
int vertice_id;
Evas_Object *o;
void *data;
}
egraph_vertice_add(Egraph *eg, const char *name, void *data);
egraph_edge_add(Egraph *eg,
const char *a, const char *b, void *data);
* speed: draw directly to a surface and map to evas via invisible polygons
see elementary/src/bin/test_gesture_layer3.c
04:45 < glouglou> i would like to draw directly in a surface and then give it to evas, but i want in the future to have user interaction with the nodes of my
graph, like click click reaction, so i guess i cannot escape from creating one evas object for each node and edge
04:46 <@raster> trick:
04:47 <@raster> u can just create invisible rects
04:47 < glouglou> (i can imagine crazy mapping of the clicks on my surface that triggers evas callbacks, but i'm not that crazy)
04:47 <@raster> and overlay them on your image
04:47 <@raster> use them for event stuff
04:47 < glouglou> lol
04:47 <@raster> or polygons tyoo
04:47 <@raster> thats about the only use of polygons
04:47 <@raster> as u can do exact inside/outside poly checks for events
04:48 < glouglou> i think you are talking about the crazy things i don't want to do :p
04:48 <@raster> one of the elm demos does this
04:48 <@raster> for soming/rotating with little photos
04:48 <@raster> multitouch test stuff
* speed: from Thanatermesis :

renders to OpenGL directly
