I am having some seemingly basic problems using the TreeWidget
from DLangUI on Windows. I posted on the project's gitter
channel some time ago but did not get any response.
All I am trying to do is add children to the tree's nodes at
runtime. The simple code below attempts to add a new node when a
button is pressed. As far as I can tell, the node does indeed
get added, since the new node responds to keyboard events, but it
does not render. I have tried everything to get it to render,
using all the available invalidate/redraw methods, even as far as
removing and re-adding the control again to its layout, but
nothing seems to work. Any advice would be greatly received!
extern (C) int UIAppMain(string[] args) {
auto window = Platform.instance.createWindow("DlangUI example
- HelloWorld", null);
auto vlayout = new VerticalLayout();
TreeWidget tree = new TreeWidget("Root");
TreeItem tree2 = tree.items.newChild("machinesroot",
"Machines"d, null);
auto machine0 = tree2.newChild("machine0", "Machine 0"d, null);
machine0.newChild("machine0stack", "Stack", null);
auto btn = (new Button("btn1", "Button 1"d));
btn.click = delegate(Widget src) {
// this gets added but does not render
tree2.newChild("machine1", "Machine 1"d, null);
return true;
};
vlayout.addChild(btn);
vlayout.addChild(tree);
window.mainWidget = vlayout;
window.show();
return Platform.instance.enterMessageLoop();
}
Thanks

It's known issue:

Not sure if there is any workaround.
