Hi,
I suspect I'm missing something obvious, but ResizerWidget is not
working for me on Windows - it shows the 'dragging'-cursor when
hovering the mouse on the ResizerWidget, but dragging with the
left mouse button does nothing.
Reduced very simple example:
///app.d
import dlangui;
import gui;
mixin APP_ENTRY_POINT;
/// entry point for dlangui based application
extern (C) int UIAppMain(string[] args) {
// create window
Window window = Platform.instance.createWindow("DlangUI
example", null);
//Make main layout
auto mainGui = new GuiHandler();
window.mainWidget = mainGui.makeGui(window);
// show window
window.show();
// run message loop
return Platform.instance.enterMessageLoop();
}
/// gui.d
import dlangui;
class GuiHandler : ResizeHandler {
Widget makeGui(Window w) {
//Make main layout
auto vlayout = new VerticalLayout();
vlayout.margins = 20;
vlayout.padding = 10;ets
vlayout.backgroundColor = 0xFFFFC0;
vlayout.layoutWidth(FILL_PARENT).layoutHeight(FILL_PARENT);
// Layout for editors
auto editorsLayout = new LinearLayout();
editorsLayout.orientation = Orientation.Vertical;
//Make edit + trace windows
auto editor = new EditBox();
editorsLayout.addChild(editor);
auto resizer = new ResizerWidget();
// resizer.resizeEvent.connect(this); //Connect for handling
events in onResize.
editorsLayout.addChild(resizer);
auto tracer = new LogWidget();
editorsLayout.addChild(tracer);
editorsLayout.layoutWidth(FILL_PARENT).layoutHeight(FILL_PARENT);
vlayout.addChild(editorsLayout);
return vlayout;
}
override void onResize(ResizerWidget source, ResizerEventType
event, int currentPosition) {
//Not shown...
}
}
I searched through all the dlangui examples where ResizerWidget
is used, and none of them provides any onResize event handler as
shown above. But, since none of them work (symptoms exactly the
same as mine), I am wondering if this is required?
Also checking in DlanguiIDE - nowhere does it implements the
onResize event handler for ResizerWidget either. I find this a
bit odd - in none of the projects where ResizerWidget are used
does it work, but none of these projects provide the onResize
event handler either. Which makes me suspect it is supposed to
work 'out of the box' and does not require the event handler for
the basic dragging functionality - similar how resizing the whole
window works without requiring that you implement it yourself in
the OnResize event handler for the main Widget. Also - I can
hardly believe that Vadim would have kept putting it in examples,
but without it working, so I suspect some regression here if I am
not doing something stupid myself (which is always possible!).
There are plenty of 'deprecated' warnings when building dlangui
and, since dlangui has not been updated since 2018, I'm concerned
it may be breaking with new versions of the compiler.
Alternatively I'm missing something elementary here..? Has anyone
used ResizerWidget successfully with a recent version of the
compiler on Windows?
