In this example we have to define our new widget type first, then we have to
|
||||
declare a variable of that type and pass that variable to the init() proc.

|
||||
Often GTK beginners ask how one can apply custom styles to GTK widgets, for example custom colors.
|
||||
While in most cases the use of custom colors gives just ugly results, as the custom colors generally do
|
||||
not match well with the default color scheme, it is good to know how we can do it. For GTK3 styles are
|
||||
applied to widgets by using _Cascading Style Sheets_ (_CSS_). You may find C example code similar to this:
|
||||
|
||||
[[label.c]]
|
||||
[source,c]
|
||||
.label.c

|
||||
// gcc `pkg-config gtk+-3.0 --cflags` test.c -o test `pkg-config --libs gtk+-3.0`
|
||||
#include <gtk/gtk.h>
|
||||
int main(int argc, char *argv[]) {
|
||||
gtk_init(&argc, &argv);
|
||||
GtkWidget *window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
|
||||
GtkWidget *label = gtk_label_new("Label");
|
||||
GtkCssProvider *cssProvider = gtk_css_provider_new();
|
||||
char *data = "label {color: green;}";
|
||||
gtk_css_provider_load_from_data(cssProvider, data, -1, NULL);
|
||||
gtk_style_context_add_provider(gtk_widget_get_style_context(window),
|
||||
GTK_STYLE_PROVIDER(cssProvider),
|
||||
GTK_STYLE_PROVIDER_PRIORITY_USER);
|
||||
g_signal_connect(window, "destroy", G_CALLBACK(gtk_main_quit), NULL);
|
||||
gtk_container_add(GTK_CONTAINER(window), label);
|
||||
gtk_widget_show_all(window);
|
||||
gtk_main();
|
||||
}

Converting that to Nim is again straight forward:
|
||||
|
||||
[[label.nim]]
|
||||
[source,nim]
|
||||
.label.nim
|
||||
----
|
||||
# nim c label.nim
|
||||
import gintro/[gtk, glib]
|
||||
import gintro/gio except Application, newApplication
|
||||
|
||||
proc activate(app: Application) =
|
||||
let window = newApplicationWindow(app)
|
||||
let label = newLabel("Yellow text on green background")
|
||||
let cssProvider = newCssProvider()
|
||||
let data = "label {color: yellow; background: green;}"
|
||||
#discard cssProvider.loadFromPath("doesnotexist")
|
||||
discard cssProvider.loadFromData(data)
|
||||
let styleContext = label.getStyleContext
|
||||
assert styleContext != nil
|
||||
addProvider(styleContext, cssProvider, STYLE_PROVIDER_PRIORITY_USER)
|
||||
window.add(label)
|
||||
showAll(window)
|
||||
|
||||
proc main =
|
||||
let app = newApplication("org.gtk.example")
|
||||
connect(app, "activate", activate)
|
||||
discard run(app)
|
||||
|
||||
main()
|
||||
----
|
||||
|
||||
For this example we create a plain label widget with some text. To colorize it, we generate a
|
||||
CssProvider and load it with a textual description of of our desired colors. Then we extract the
|
||||
style context from the label and add our CssProvider to it.
|
||||
|
||||
The last parameter of the _C_ function gtk_css_provider_load_from_data() is of type GError and can
|
||||
be used in _C_ code to detect runtime errors. The _C_ code above just passes NULL to ignore this error.
|
||||
For Nim we map that GError argument to _exceptions_. To test what happens in Nim when an GError would
|
||||
report an error condition, you may uncomment function loadFromPath() in the code above. As the specified path
|
||||
does not exist, we should get an exeption with a message telling us the problem. Of course in your real
|
||||
code you may catch such exceptions with Nim's `try:` blocks. (You may also modify the data variable above to
|
||||
an illegal CSS statement -- if the statement is seriously wrong, then you should get an exception from
|
||||
loadFromData().
