Asked on Riot (via Rust ♥ GNOME), but does anybody have some good examples of async image loading?
I've been sifting through examples and did find one that seemed sort of helpful, but I'm struggling to tie it into my app right now
https://github.com/foldu/iv2/blob/310fe06030f9d538ba1a591f07a5a149b7890c7d/src/context.rs#L29
Still struggling with futures, though, and can't seem to get images to load in the background...

My scenario: I have a
I get a list of image paths and load those into the flowbox via a
I want to defer the image loading and not block the main thread when all that is happening

Ironically, I found this post the day I picked this project up again... https://blog.gtk.org/2020/06/07/scalable-lists-in-gtk-4/
And even then... I wonder how much I'd have to change with my app...
GtkGridView looks like it's exactly what I need right now... 🤤 But that's gtk4 only, and as far as I can tell, gtk-rs/{gtk4, gir} aren't there, yet, IIUCAnd even then... I wonder how much I'd have to change with my app...
Hello everyone ! I am trying to use the clone macro for a closure. But it seems I can't use for fields access :
fn build_widget(state: &ChessBoardState) -> DrawingArea {
let area = DrawingArea::new();
let size = state.size;
area.set_size_request(size, size);
area.connect_draw(clone!(@weak state => |_source, context| {
let (bg_red, bg_green, bg_blue) = state.background_color;
context.set_source_rgb(bg_red, bg_green, bg_blue);
context.paint();
Inhibit(false)
}));
area
}I got Variables need to be valid identifiers, e.g. field accesses are not allowed as is, you must rename it!. So using state variable as is is not possible, so is there a workaround ?
adjivas Hello, the gtk4 examples are always buildable? I'm not sure which rust's version to use. https://github.com/gtk-rs/examples4
I tried grabbing a pixbuf of my screen, but I fail to retrieve the window surface using "offscreen_window_get_surface".
Are there any other API endpoints to grab the surface of the root window, or am I missing something?
Here's the code: https://gist.github.com/eHammarstrom/cf465d20690368dc1f5f9a7aaa482ff1
Hello. I'm attempting to get this working on Windows, and after running into a linker error, found out I need to install GTK, which isn't straightfwd. I'm making a very simple GUI app that anyone on Windows, Linux, or Mac should be able to use. Is this possible, or does it need system dependencies to run? Thank you.
hi @David-OConnor I made it work on windows many years ago, you can try the steps here https://github.com/kc1212/convolutional-stack#install-on-windows
The block_on fn on main context states that "This must only be called if no MainLoop or anything else is running on this specific main context.". Does this mean that one should not call block_on within the main thread? https://gtk-rs.org/docs/glib/struct.MainContext.html#method.block_on
but no dialog shows up
i want to have the dialog show up, and also actually put some text in it (see commented out line). And access the gtk::ResponseType for the button value from it. how can i do these?
i get no errors
Hey guys, I would like to draw nodes and lines between those nodes. These graphs will be used to simulate algorithms on them. At which structs should I take a look?
My use case is:
- draw n nodes and give them a color
- connect some of the nodes with a straight line also in a specific color
gondolyr Hey everyone, I'm looking to start a project with libhandy but when I go to build, I get failed to add UI: .:7:1 Invalid object type 'HdyApplicationWindow'. I've installed libgtk-3-dev and libhandy-0.0-0, though I'd like to use libhandy-1 when it's available from the Debian repository. Also, if anyone has a handy tutorial, I'd appreciate that as well.
mmstick > <@vancha112:matrix.org> hey everyone ^^ I'm looking to increase the size of my text in gtk-rs. I knew that gtk could make use of css for increasing for example text size, but I don't know how to do so in gtk-rs :(
You could use CSS, but pango also works for modifying text attributes.
how do I get the app to close?
my code currently looks like this
use gtk::prelude::*;
fn main() {
if let Err(msg) = gtk::init() {
println!("Failed to initialize GTK: '{}'", msg);
return;
}
let layout_src = include_str!("../res/gui_layout.glade");
let builder = gtk::Builder::from_string(layout_src);
let window: gtk::Window = builder.get_object("window").unwrap();
window.show_all();
gtk::main();
}
what does the gtk::Inhibit do?
mmstick It won't do anything here since gtk::main_quit() will quit the application
Timo Is it broken atm?

Does anyone have any experience getting GTK3 working on windows (through either native or cross compilation). I'm trying to follow https://gtk-rs.org/docs-src/tutorial/cross but am having trouble finding distros of the correct versions of GTK3 compiled with MinGW
felinira What is the difference between https://github.com/gtk-rs/gtk-rs/tree/master/glib and https://github.com/gtk-rs/glib ?
