[Vala] [vala] getopt

[David Boesner]

Hi everyone,

I want to extract which parameters and values I have passed to my program.
I used getopt, when I solved that problem in c. Is there an vala
counterpart to getopt?

Regards David

[Vala] bind_property BindingTransformFunc

[David Boesner]

Hi guys,
I have to follwing code:

var check_button = ... make instance of Gtk.CheckButton

var my_combobox = ... make instance of Gtk.ComboBox


check_button.bind_property(
"active",
my_combobox, "sensitive",
BindingFlags.INVERT_BOOLEAN,
(binding, source_value, target_value)=>{
if(source_value == true){
print("\n I get here");
my_combobox.active_id =
"TSS_SECRET_MODE_SHA1";
}

return true;
}
);

The problem is, that my_combobox doesn't become sensitive,
if I de-activate the check_button. Why?

The active_id is chosen correctly.

Thanks in advance.

Regards

[Vala] Solved: Gtk+-3.0 Gtk.Entry fontcolor

[David Boesner]

Hi,

I've found the solution. The method I've used is deprecated.
This works:

var red = RGBA();
red.parse("#ff");

my_entry.override_color(StateFlags.NORMAL, red);

[Vala] Gtk+-3.0 Gtk.Entry fontcolor

[David Boesner]

Hi everyone,

I try to change the color of the text in a Gtk.Entry.
I try it this way:

Gdk.Color red;
if(Gdk.Color.parse("RED",out red)==true);
print("\that works"); // that gets printed

if(my_entry.text.length >= 9 && !(my_entry.text[8].to_string()
== "-")){ //my_entry = Gtk.Entry

print("\n I get to here"); // this also gets displayed
my_entry.modify_text(my_entry.get_state(), red);
}
The problem is, that the color doesn't change. It stays the same.
I'm using Gtk3

Regards

And I wonder what the @see taglet should be good for.
I'm missing an exlpaination there.

Thanks in advande

[Vala] false: #include GirName.h

[David Boesner]

Hi everyone,

I'm new to vala. Right now I'm working on a project which uses several
GObject classes and
tries to access them in a vala file throught GObject introspection.

The strange this is, that when I try to compile my vala file
Vala tries to include a headerfile (in the c header file, which is created
based on my vala file)
with the name as my .gir file, which I use
for introspoection. This headerfile surely doesn't exist and thus I can't
compile my program.

Does anyone know the reason for this strange behaviour?

Thanks in advance

[Vala] Segfault

[David Boesner]

Hi everyone,

I'm very new to vala (know it since yesterday). Right now I'm through the
tutroial.

I was playing around with classes and interfaces a bit.

While trying out some stuff I produced this code:

I have no idea why I produce a segfault in the line below.

I would be very happy if someone could help me.

class SuperClass : AnotherClass {

private int data;

public SuperClass(int data) {
this.data = data;
stdout.printf("3");
//base(); // Here is a segfault
//
}

}
public class AnotherClass : GLib.Object{
public AnotherClass(){

stdout.printf("\nA");
}
}
public interface ITest: AnotherClass {
public abstract int data_1 { get; set; }
public abstract void method_1();
}

class SubClass : SuperClass, ITest {

public SubClass() {
stdout.printf("2");
base(10);

}
public int data_1 { get; set; }
public void method_1(){
stdout.printf("\n method 1");
}
}
void main(){
stdout.printf("0");
SubClass s = new SubClass();
s.method_1();
stdout.printf("1");
s = s ?? null;
}
