September 08, 2017 Problems with the DLangUI TreeWidget | ||||
---|---|---|---|---|
| ||||
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 |

Ah, thanks for the reply. I did check the issues on git, obviously not well enough!
That's a shame, it renders (no pun intended) DLangUI basically useless for my project :( maybe I will have to get the debugger out ...
