Selectable tree node

[ghost]

Hi,

I need a tree with selectable nodes. The current tree does not allow this. I have try using "Selectable+Indent" as leaf and normal tree node for inner nodes but:

• only the selectable are "selectable"
• the selectables (even with Indent) are not well aligned with the tree node.

So, I think to create my own TreeNode like widget, here is my current code:

bool SelectableTreeNode(const char* label, bool isSelected, bool hasChildren)
{
    // Selection
    if (isSelected)
    {
        ImU32 col = ImColor(ImGui::GetStyle().Colors[ImGuiCol_HeaderHovered]);
        /*x += os.x;
        y += os.y;
        ImGui::RenderFrame(ImVec2(x, y), ImVec2(x + itemFullWidth, y + itemFullHeight), col, true, 3.f);
        x -= os.x;
        y -= os.y;*/
    }

    ImGui::PushID(label);
    const bool opened = ImGui::CollapsingHeader(label, "", false);
    ImGui::PopID();

    if (opened)
        ImGui::TreePush(label);

    return opened;
}

But how can I :

• know the area of the treenode (see RenderFrame)
• Hide the Triangle/Arrow based on the "hasChildren" parameter

Any idea ?

Could you move this to #190 ?
Thanks
