Cool!
I am not really that much into qml... but isn't much of the
power of qml coming from using javascript to do logic and
bindings?
Can you do D code stuff in the DML markup to handle that part
e.g. by mixin of the DML?
Keep up the good work.

So far, I'm going to implement
* automatic mapping of loaded widgets to member variables (based
on matching of widget id and variable names, or, possible mixin
adding of member variables for all of widgets with ids)
* automatic mapping of loaded widget signals to handlers
Mixing in handlers written in D from DML is possible, in some of
future implementations. So far, I'm not sure that it's better
than just having external signal handlers automatically mapped,
e.g. by name.
sample DML:
{
HorizontalLayout {
TextWidget { text: Enter file name: }
EditLine {
id: edFileName
}
Button {
id: btnOpen
text: Open
click = onBtnOpenClick
}
}
}
...
// class members
EditLine _edFileName;
bool onBtnOpenClick(Widget src) {
window.showMessageBox(Opend, File name:d ~
_edFileName.text);
return true;
}
Member variable `EditLine _edFileName;` could be added
automatically by mixin, or at least it's value can be initialized
on load
Signal handler may be assigned either if explicitly defined in
DML (`click = onBtnOpenClick` means widget click signal should be
connected to member function onBtnOpenClick) or just found based
on widget Id and signal name (e.g. if there is widget with
id=btnOpen and class method onBtnOpenClick - loader mixin could
automatically decide to assign this method as signal handler of
widget (like it's dont in VB).
I'm not sure if alternative definition is better
Button {
id: btnOpen
text: Open
click = { window.showMessageBox(Opend, File
name:d ~ edFileName.text); }
}

If you are interested, we are doing a GUI system inspired by QtQuick/QMLEngine : https://github.com/D-Quick/DQuick

Some advanced kind of layout? yes, it's universal constraint solver that especially aimed to building GUI layouts. apple adapted it as layout engine for their macos x and ios, for example. signature.asc Description: PGP signature
