Dialog widget

Would be great if you could check Dialog Widget as I tried without success. An short example even better. Thanks.

Hi again! Can you be more specific here? The marshalling example makes use of QInputDialog, mdoutliner makes use of QFileDialog, printsupport uses QPrintDialog, and kitemviews uses QDialog directly. The first three inherit from QDialog either directly or indirectly.

Also, as part of the development to support Qt Creator, I did extensive testing which involved much use of QDialog so that is an option if you need to use it as well and need some code generated. It would be used like all of the other Qt objects in the examples based on QWidget as well. Also, there are examples that make use of QDialogButtonBox in case that is which dialog you are referring to.

Can you share exactly what issues you had?

Thanks for pointing out examples that used dialog.

I am still using a zig 0.14.1 and libqt6zig-examples accordingly. The marshalling, mdouliner, printsupport work fine. I just tried to create a simple input dialog.

const std = @import("std");
const qt6 = @import("libqt6zig");
const C = qt6.C;
const qapplication = qt6.qapplication;
const qdialog = qt6.qdialog;
const qdialogbuttonbox = qt6.qdialogbuttonbox;
const qdialogbuttonbox_enums = qt6.qdialogbuttonbox_enums;

var dialog: C.QDialog = undefined;

pub fn main() void {
    dialog = qdialog.New2();
    qdialog.SetWindowTitle(dialog, "Qt 6 Dialog");
    qdialog.SetWhatsThis(dialog, "Qt6 Dialog");

    const buttonbox = qdialogbuttonbox.New(dialog);
    qdialogbuttonbox.SetStandardButtons(buttonbox, qdialogbuttonbox_enums.StandardButton.Ok | qdialogbuttonbox_enums.StandardButton.Cancel);

    qdialog.Resize(dialog, 350, 600);
    _ = qdialog.Exec(dialog);
}

And get
error: ld.lld: undefined symbol: QDialog_new2
error: ld.lld: undefined symbol: QDialogButtonBox_new
error: ld.lld: undefined symbol: QDialogButtonBox_SetStandardButtons
error: ld.lld: undefined symbol: QDialog_Exec

I am on debian 13/Qt6.8
QMake version 3.1
Using Qt version 6.8.2 in /usr/lib/x86_64-linux-gnu

It is a linking issue, I guess.

If you are using the examples, you need to have qdialog added to the qtlibs file alongside this code. If you are using a separate build.zig configuration, you can add qdialog to the Qt libraries there. The fact that the other examples work are a good sign that things are working, just that there is possibly a configuration issue. The examples are structured as independent applications and I opted to keep their dependency structure outside of the build system. The qtlibs file included with each example instructs the build system which libraries are dependencies to build the specific application in that folder.

One key thing, you aren't initializing a QApplication instance:

    const argc = std.os.argv.len;
    const argv = std.os.argv.ptr;
    const qapp = qapplication.New(argc, argv);
    defer qapplication.QDelete(qapp);

const std = @import("std");
const qt6 = @import("libqt6zig");
const C = qt6.C;
const qapplication = qt6.qapplication;
const qdialog = qt6.qdialog;
const qdialogbuttonbox = qt6.qdialogbuttonbox;
const qdialogbuttonbox_enums = qt6.qdialogbuttonbox_enums;

var dialog: C.QDialog = undefined;

pub fn main() void {
    const argc = std.os.argv.len;
    const argv = std.os.argv.ptr;
    const qapp = qapplication.New(argc, argv);
    defer qapplication.QDelete(qapp);

    dialog = qdialog.New2();
    qdialog.SetWindowTitle(dialog, "Qt 6 Dialog");
    qdialog.SetWhatsThis(dialog, "Qt6 Dialog");

    const buttonbox = qdialogbuttonbox.New(dialog);
    qdialogbuttonbox.SetStandardButtons(buttonbox, qdialogbuttonbox_enums.StandardButton.Ok | qdialogbuttonbox_enums.StandardButton.Cancel);

    qdialog.Resize(dialog, 350, 600);
    _ = qdialog.Exec(dialog);
}

With this code, I get this:

Not really. I think its from my end as I cut and pasted your working code and still the same errors. Will do further debug and report back later. Thanks.

If you are using the examples repository structure as it is, you need to include qdialog and qdialogbuttonbox in the qtlibs file. Check the other examples for that file's contents. That is where the build system is looking for what needs to be built and included.

@rcalixte ,

Working now. You are right. Turned out I miss those lines in qtlibs.

[rcalixte]

Great to hear! For a real application, I don't think you would have these issues as you would have them broken out in the build system's configuration. Let me know if you can think of ways this could be improved! Enjoy!
