I'm not familiar with this toolkit, but my guess is that you 
didn't pass in a `flags` value and therefore you aren't using 
the appropriate overload of the createWindow() function to 
achieve what you're after.


The following is from the DLangUI GitHub site 
(https://github.com/buggins/dlangui/wiki/Getting-Started). Take 
a look at the third argument:


Window createWindow(
dstring windowCaption, // window caption
Window parent, // parent window, pass null for main 
(first) window.
uint flags = WindowFlag.Resizable, // various flags - bit 
fields from WindowFlag enum values

uint width = 0,// initial window width
uint height = 0// initial window height
);


Thanks for the reply, Ron.

Yes, as you say WindowFlag.Resizable is the default value for the 
'flags' argument in the createWindow call, so that was the 
setting I had.


But the problem is actually not in resizing the full app window 
(that actually works - including keeping the relative proportions 
of the widget children sizes), but rather in resizing 2 widgets 
that are separated by a ResizerWidget inside the app window. The 
app window size should actually not be affected since, as 1 
widget on one side of the ResizerWidget shrinks by N pixels in 
height or width (depending on the orientation of the 
ResizerWidget), the opposite widget should grow by the same N 
pixels in height/width, leaving the parent size unaffected.


I can see that is actually what is coded, but it is not working 
when I run the app.


But I thought you may be on to something and I should check if 
children widgets of the app window inherits some settings from 
the parent, so I checked the WindowFlag flags. According to [1] 
you can have:

- Fullscreen
- Modal
- Resizable

However, checking the code there are additional options:
/// window creation flags
enum WindowFlag : uint {
/// window can be resized
Resizable = 1,
/// window should be shown in fullscreen mode
Fullscreen = 2,
/// modal window - grabs input focus
Modal = 4,
/// measure window size on window.show() - helps if you want 
scrollWindow but on show() you want to set window to mainWidget 
measured size

MeasureSize = 8,
/// window without decorations
Borderless = 16,
/// expand window size if main widget minimal size is greater 
than size defined in window constructor

ExpandSize = 32,
}

So it looks like the documentation isn't completely up to date 
either. Anyway, I also tried to pass WindowFlag.Resizable | 
WindowFlag.MeasureSize as flags argument in the call to 
createWindow, but it did not help.


I was hoping for a quick answer on the forum from someone who has 
run into the same, but I think I'm going to need to dig into 
dlangui code to figure out what is going wrong.

I cannot do any work, since LLD-link is broken and doesn't want 
to link for anything. It just gives me a bunch of errors for 
missing symbols, that supposed to be in the core libraries.


How can I set up the Microsoft linker instead?

hi, if you have the latest code-d version for vscode 
(webfreak.code-d) you can check in the User Guide (F1 -> code-d 
user guide) that it has a section about debugging you can check 
out which should guide you through all the steps to debug.


In there you should find all information you need.

Compile what?
You successfully compiled and ran your dub build.

Please note the default action is to run, so using `dub` by 
itself is equivalent to `dub run`. Hence the recursive 
executions.


Use `dub build` if all you want to do is build.


In addition to that, there are different ways how you can 
contribute to Dub:


- enhancing the dub help on code.dlang.org
- finding duplicate/already solved issues on the github issue 
tracker


Especially the issues list is a good starting point for new

Hello everyone, I was interested in contributing to the DUB 
project. So, I forked the repo, installed DMD and libcurl as 
instructed in the README. I ran build.sh inside the repo. It then 
creates a dub executable inside of bin folder. After that I was 
stuck as there was no documentation on how to make changes or how 
to compile the thing. I then ran ./bin/dub and it started some 
compilation. The linking also worked. After that I see this :
