How to pass ListStore to functions in a GTK4 application? (original) (raw)
December 13, 2024, 12:42pm 1
Hello!
I am trying to create an application using C and GTK4, but I am a little lost here. I have defined a menu item “Open file…” which a user can use to retrieve a file and then the application should parse the file, line-by-line, into a ListStore so it could be shown in an GtkColumnView. I don’t know how or what is even the correct way to pass my ListStore for “open_file_complete” function so the contents could be added to that ListStore. Can someone help me out?

You can build it using (name the paste as “example.c”):
gcc -Wall <span class="katex"><span class="katex-mathml"><math xmlns="http://www.w3.org/1998/Math/MathML"><semantics><mrow><mo stretchy="false">(</mo><mi>p</mi><mi>k</mi><mi>g</mi><mo>−</mo><mi>c</mi><mi>o</mi><mi>n</mi><mi>f</mi><mi>i</mi><mi>g</mi><mo>−</mo><mo>−</mo><mi>c</mi><mi>f</mi><mi>l</mi><mi>a</mi><mi>g</mi><mi>s</mi><mi>g</mi><mi>t</mi><mi>k</mi><mn>4</mn><mo stretchy="false">)</mo><mo>−</mo><mi>o</mi><mi mathvariant="normal">"</mi><mi>e</mi><mi>x</mi><mi>a</mi><mi>m</mi><mi>p</mi><mi>l</mi><mi>e</mi><mi mathvariant="normal">"</mi><mi mathvariant="normal">"</mi><mi>e</mi><mi>x</mi><mi>a</mi><mi>m</mi><mi>p</mi><mi>l</mi><mi>e</mi><mi mathvariant="normal">.</mi><mi>c</mi><mi mathvariant="normal">"</mi></mrow><annotation encoding="application/x-tex">(pkg-config --cflags gtk4) -o "example" "example.c" </annotation></semantics></math></span><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:1em;vertical-align:-0.25em;"></span><span class="mopen">(</span><span class="mord mathnormal">p</span><span class="mord mathnormal" style="margin-right:0.03148em;">k</span><span class="mord mathnormal" style="margin-right:0.03588em;">g</span><span class="mspace" style="margin-right:0.2222em;"></span><span class="mbin">−</span><span class="mspace" style="margin-right:0.2222em;"></span></span><span class="base"><span class="strut" style="height:0.8889em;vertical-align:-0.1944em;"></span><span class="mord mathnormal">co</span><span class="mord mathnormal">n</span><span class="mord mathnormal" style="margin-right:0.10764em;">f</span><span class="mord mathnormal">i</span><span class="mord mathnormal" style="margin-right:0.03588em;">g</span><span class="mspace" style="margin-right:0.2222em;"></span><span class="mbin">−</span><span class="mspace" style="margin-right:0.2222em;"></span></span><span class="base"><span class="strut" style="height:1em;vertical-align:-0.25em;"></span><span class="mord">−</span><span class="mord mathnormal">c</span><span class="mord mathnormal" style="margin-right:0.10764em;">f</span><span class="mord mathnormal" style="margin-right:0.01968em;">l</span><span class="mord mathnormal">a</span><span class="mord mathnormal" style="margin-right:0.03588em;">g</span><span class="mord mathnormal">s</span><span class="mord mathnormal" style="margin-right:0.03588em;">g</span><span class="mord mathnormal">t</span><span class="mord mathnormal" style="margin-right:0.03148em;">k</span><span class="mord">4</span><span class="mclose">)</span><span class="mspace" style="margin-right:0.2222em;"></span><span class="mbin">−</span><span class="mspace" style="margin-right:0.2222em;"></span></span><span class="base"><span class="strut" style="height:0.8889em;vertical-align:-0.1944em;"></span><span class="mord mathnormal">o</span><span class="mord">"</span><span class="mord mathnormal">e</span><span class="mord mathnormal">x</span><span class="mord mathnormal">am</span><span class="mord mathnormal" style="margin-right:0.01968em;">pl</span><span class="mord mathnormal">e</span><span class="mord">""</span><span class="mord mathnormal">e</span><span class="mord mathnormal">x</span><span class="mord mathnormal">am</span><span class="mord mathnormal" style="margin-right:0.01968em;">pl</span><span class="mord mathnormal">e</span><span class="mord">.</span><span class="mord mathnormal">c</span><span class="mord">"</span></span></span></span>(pkg-config --libs gtk4)
And another thing, if you see errors or mistakes in my code, please tell me about those so I could fix them and learn something in the process 
Thanks in advance!
