Hello,
is it possible, to delete a selected TreeView SubItem with a
Button-Click?
My Code currently looks like this:
import gtk.MainWindow;
import gtk.Box;
import gtk.Main;
import gtk.Button;
import gdk.Event;
import gtk.Widget;
import List, Languages;
void main(string[] args){
Main.init(args);
MainWindow win = new MainWindow("TreeView Example");
win.setDefaultSize(500,300);
Box box = new Box(Orientation.VERTICAL, 0);
auto list = new List();
auto german = list.addCountry("German", "Germany");
auto city = list.addCountryCity(german, "German", "Munich");
auto sweden = list.addCountry("Swedish", "Sweden");
auto cit = list.addCountryCity(sweden, "Swedish", "Stockholm");
auto treeView = new LanguageTree(list);
box.packStart(treeView, true, true, 0);
auto btn_Delete = new Button("Delete");
box.add(btn_Delete);
win.add(box);
win.showAll();
Main.run();
}
class DeleteButton : Button
{
this(in string text)
{
super(text);
addOnButtonRelease();
}
private bool del(Event event, Widget widget)
{
return true;
}
}
But i neither know how i get the currently selected item nor
how i could delete it within the "del"-Event of the
"DeleteButton"?
TreeIter iter = treeView.getSelectedIter;
then you can use the TreeIter to delete the item.
If your List is a ListStore or TreeStore, it has a remove method
that you can call.
If its a custom store you will have to implement it yourself like
this
class List:TreeModel
{
.
void remove(TreeIter iter)
{
//maybe remove item from your actual data structure or other
processing
//send rowDeleted signal
rowDeleted(iter);
}
.
}

So like this?
public void remove(TreeIter iter)
{
this.remove(iter);
}
If i do this, i get a stackoverflow error :(
Your List inherits from TreeStore correct? just get rid of your
custom remove method entirely, or correctly override it
public override void remove(TreeIter iter)
{
super.remove(iter);
}

I wrote a custom OBJ file importer which worked fairly well
however was not robust enough to support everything. I've
decided to give AssImp a shot. I followed some tutorials and
have set up my code to read in the vertices, tex coords,
normals, and indices of an OBJ cube model that I have had
success loading with my custom importer. The cube model's faces
do not render properly, instead only rendering a few tri's of
the cube. The way AssImp handles the data is obviously a bit
different than my solution because the normals,
positions/vertices, tex coords, and indices do not match my
custom solution. I would very much appreciate some insight into
why I'm having issues as all of the tutorials I've found have
matched my approach. If a picture of the faulty rendered cube
would be helpful I can work on getting a screenshot up. Thank
you.

Imagine a square mesh made up of two triangles, the un-indexed
version has 6 vertices, but the indexed version that you would be
using has 4 vertices because a side is shared by the two
triangles (which is managed by the index array). This is why you
can't assume each face has 3 vertices.
I have been trying to learn opengl and D recently together and
this is the simple code I have been using to load models from
assimp.
for(int i = 0; i mesh.mNumVertices; i++)
{
aiVector3D vert = mesh.mVertices[i];
verts ~= vec3(vert.x, vert.y, vert.z);
aiVector3D uvw = mesh.mTextureCoords[0][i];
uvs ~= vec2(uvw.x, uvw.y);
aiVector3D n = mesh.mNormals[i];
normals ~= vec3(n.x, n.y, n.z);
}
for(int i = 0; i mesh.mNumFaces; i++)
{
const aiFace face = mesh.mFaces[i];
indices ~= face.mIndices[0];
indices ~= face.mIndices[1];
indices ~= face.mIndices[2];
}
