Here my simple example on Nim:
import gintro/[gtk4, gobject, gio]
import std/with, os
type
ControlWithMediaFile = tuple
file: MediaFile
controls: MediaControls
proc entryChanged(self: EntryBuffer, position: int, chars: string, nChars: int, media: ControlWithMediaFile) =
echo self.text
if os.fileExists(self.text):
media.file.clear
media.file.setFilename self.text
proc appActivate(app: Application) =
let
window = newApplicationWindow(app)
mainBox = newBox(Orientation.vertical, 3)
mediaFile = newMediaFileForFilename("5minAudio.mp3")
mediaControls = newMediaControls(mediaFile)
mediaPathEntry = newEntry()
mediaPathEntry.placeholderText = "Enter music filename"
mediaPathEntry.buffer.connect("inserted_text", entryChanged, (mediaFile, mediaControls))
with mainBox:
append mediaPathEntry
append mediaControls
with window:
child = mainBox
title = "MediaControls"
defaultSize = (250, 0)
show
proc main =
let app = newApplication("org.gtk.example")
connect(app, "activate", appActivate)
discard run(app)
main()
When I change the Media File for Media Controls, the timeline parameters are not updated in Media Controls.
