GTK+ 2.0 Text Editor in C++

[theopfor]

I am currently making a text editor using GTK+ 2.0. I am programming it in C++. The editor currently has a good start, but is rather bland.

http://theopfor.pcriot.com/stuff/TextEditor.png

So, now I need to add something to make it more, visually appealing. It's lacking some items, but, currently, I'm looking more towards quality over quantity.

How do I add buttons with images on them? I am making the buttons from stock.

How do I get my file chooser dialog to work? It will pop everything up, but not save anything, or load anything, and I don't understand why.

How do I add more libraries to the code? Whenever I do, I get an error. Since I am making this in C++, I have to compile it in terminal with
gcc main.cpp -o compiled `pkg-config --cflags --libs gtk+-2.0` (Code::Blocks will only compile GTK+ programs in C).

Here is the code:


//Text editor
#include <gtk/gtk.h>

////////////////////
// GLOBAL //
///////////////////

static GtkWidget *window, *text, *tabs;


static GtkTextBuffer *buffer;


/////////////////////////

//When the quit button is pressed
static void quit(GtkWidget *window, gpointer data){
gtk_main_quit();
}

/*static void newDoc(GtkWidget* widget, gpointer data){
gtk_notebook_append_page(GTK_NOTEBOOK(notebook), text, defaultTitle);
};*/

static void fileOpen(GtkWidget *load, gpointer window){
GtkWidget *choose;

choose = gtk_file_chooser_dialog_new("Choose a file to open", GTK_WINDOW(window), GTK_FILE_CHOOSER_ACTION_OPEN, GTK_STOCK_OK,
GTK_RESPONSE_OK, GTK_STOCK_CANCEL, GTK_RESPONSE_CANCEL, NULL);
if (gtk_dialog_run(GTK_DIALOG(choose)) == GTK_RESPONSE_ACCEPT){

char *path = gtk_file_chooser_get_filename(GTK_FILE_CHOOSER(cho ose));
gtk_text_buffer_set_text(buffer, path, -1);
}

gtk_widget_destroy(choose);
}

static void fileSave(GtkWidget *save, gpointer window){
GtkWidget *saved;

saved = gtk_file_chooser_dialog_new("Choose a file to open", GTK_WINDOW(window), GTK_FILE_CHOOSER_ACTION_SAVE, GTK_STOCK_OK,
GTK_RESPONSE_OK, GTK_STOCK_CANCEL, GTK_RESPONSE_CANCEL, NULL);
gtk_widget_show_all(saved);

gint resp = gtk_dialog_run(GTK_DIALOG(saved));

gtk_widget_destroy(saved);
}

}Thanks ahead of time! :D

1. Install the "build-essential" package.
2. Create an empty C++ project in Code::Blocks
3. Use Gtkmm(these are C++ bindings for Gtk+). DOn't forget to install libgtkmm-dev. www.gtkmm.org
4. Redo your code using Gtkmm
5. Use Gtk::Button::set_image() (http://developer.gnome.org/gtkmm/unstable/classGtk_1_1Button.html#ac49972018a8ed3392e897cdf9 da66391).
6. If you insist on using the C API then use gtk_button_set_image() (http://developer.gnome.org/gtk3/stable/GtkButton.html#gtk-button-set-image).

(In codeblocks: open your projects settings and insert in the compiler's custom/extra flags " 'pgk-config gtkmm-2.4 --cflags' " and in the linker's custom/extra flags " 'pgk-config gtkmm-2.4 --libs' ")

:confused:I'm confused on the part where I change the compiler and linker settings. I don't see an area to copy and paste anything. In Compiler Flags, I see a bunch of check boxes, but nothing to copy and paste. In the linker settings, I am just 100% confused with.

Any way you could explain it very throughly? I have never opened that section of the IDE.

[SledgeHammer_999]

1. Project->Build Options
2. Compiler Settings -> Other options. Paste: 'pgk-config gtkmm-2.4 --cflags'
3. Linker Settings -> Other Linker options. Paste: 'pgk-config gtkmm-2.4 --libs'
4. Don't forget the ' in the above commands.
5. It should compile now.

g++ fatal error: no input files

I did what you said, but I don't understand that error...
