kandi X-RAY | flowbox Summary
this is a proof of concept to implement an infosphere streams-like (and esper-like) distributed complex event processing engine written on top of apache storm. this framework’s goal is to make use of storm’s groupings and tuple-at-a-time abilities (along with its guarantees of thread-safe parallelism in its bolts) to make different processed flows of streams possible in a single storm topology. trident is wonderful for building out streams of data and defining how to process those streams along the way, however each each trident topology needs to be deployed separately in storm. you could, perhaps, write several streams in a trident topology, but this problem is exasberated by massive complexity in the client-side builder pattern required to make it possible. similar to hadoop mapreduce, a storm cluster is run with a finite amount of resources available. each topology that gets deployed needs to make use of more resources. if i have 15 different analytics that i’m interested in writing to correllate the same couple streams of data, i’m left running 15 different topologies. one of the

QUESTION
I'm using a Gtk.FlowBox with a number of Gtk.FlowBoxChild children. Based on buttons selected by a user I'm applying different Gtk.FlowBoxFilterFunc functions. I would like to determine at any point in time how many of the children are visible (i.e. unfiltered). I've tried checking all the various visible, no_show_all properties, as well as the is_visible(), get_visible() functions. I can't seem to find any property or method for determining which children are unfiltered - is this possible?
I've noticed that when I use the GTK Inspector for debugging, it seems to detect the change, because the text in the hierarchy tree changes from black go grey. This makes me think that it must be possible somehow!

...ANSWER
Answered 2022-Mar-19 at 17:47This is possible using the get_mapped() method on the Gtk.FlowBoxChild widget.
Like @BobMorane mentioned in the comments, the GTK documentation has the following entry for the map signal:
A widget is mapped when the widget is visible (which is controlled with GtkWidget:visible) and all its parents up to the toplevel widget are also visible. The ::map signal can be used to determine whether a widget will be drawn

I am working on (py)gtk4's drag-and-drop functionality and I hit a wall. I have a flowbox-derived class MediaGallery that contains frames with images and their filenames (class MediaFile), and a listbox-derived class Albums. I want to drag one or more selected images from MediaGallery to Albums, which will eventually add them to the underlying database.

For example here it is changed to use a gliststore to store multiple items in a single GObject and from that create a GValue:
QUESTION
When I use Gtk.FlowBox.select_child() programmatically the selection works fine. But if I use arrow keys to move the selection afterwards, it ignores the previously selected item and moves from the first item in the FlowBox. I don't know if this is a bug or I have to do something else to make the cursor know the new location. Selecting with mouse works as expected.
I'm using gtk3 version 3.24.23 on Linux.

QUESTION
I created a program that outputs CSV formatted tags based on checkbuttons.. There's a LOT of them so it only makes sense to create them programmatically.. I was successful in that sense, but I was never able to figure out how to get their checked state since you can't access them like normal checkbuttons. I worked around it, but now getting to the 'polishing' phase of my program, I'd REALLY like to be able to reset the form by unchecking them all, and I can't figure out how to access them.. First, here's how the checkbuttons are created dynamically:
...ANSWER
Answered 2020-Nov-12 at 22:11First of all, it doesn't make sense to use a global GtkWidget* or GtkCheckButton*, since you have multiple of them anyway, so each time you create a new one, it will overwrite the old value.
Next, there are 2 ways of still accessing those buttons:
Like Alexander suggested in the comments, you can keep a list of
GtkWidget*orGtkCheckButton*(and add your buttons as you create them on the go). That way, you can iterate over the array and uncheck them all.Another option is to use the parent container of all the check buttons, by iterating over its children (but that really assumes you don't have any other GtkCheckButtons in there!)

Install flowbox
You can use flowbox like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the flowbox component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
