I got this warning with gtkCode:warning: assignment discards qualifiers from pointer target type
here is my codeCode:- Function: gchar* gtk_entry_get_text (GtkEntry *ENTRY)
Returns the text that is contained in the `GtkEntry' as a pointer
to a `gchar' variable.
what does this mean?Code:gchar *input;
.
.
.
input=gtk_entry_get_text(GTK_ENTRY(GTK_COMBO(combo)->entry));
Thanks
>warning: assignment discards qualifiers from pointer target type
What's the type of "GTK_ENTRY(GTK_COMBO(combo)->entry)"? Does it have a const or volatile qualifier?
I don't know what a qualifier is.
here is
I dont' think that helps though. Entry can change so i'd say that's volatile but i'm not about GTK_ENTRYCode:GtkWidget *combo;
combo=gtk_combo_new();
>I don't know what a qualifier is.
const and volatile are qualifiers. They add restrictions or further information to a type.
It can be changed, so it is voilatile?Quote:

Where the GtkWidget is defined?[edit] And other stuff.
volatile is a keyword to tell the compiler not to cache the value of the variable between statements because the variable can be changed outside the program, by a different thread for example. It's not used very often.
You probably know what a const qualifier is: it specifies that the given variable cannot be changed.
[edit] A GtkWidget is defined as this:
From http://developer.gnome.org/doc/API/2...GtkWidget.html [/edit]Code:typedef struct {
/* The style for the widget. The style contains the
* colors the widget should be drawn in for each state
* along with graphics contexts used to draw with and
* the font to use for text.
*/
GtkStyle *style;
/* The widget's desired size.
*/
GtkRequisition requisition;
/* The widget's allocated size.
*/
GtkAllocation allocation;
/* The widget's window or its parent window if it does
* not have a window. (Which will be indicated by the
* GTK_NO_WINDOW flag being set).
*/
GdkWindow *window;
/* The widget's parent.
*/
GtkWidget *parent;
} GtkWidget;
