Notices

I need something like the color selector on the calendar > setting
(to select the color of the event category)

i manage to implement something similar using
hildon.Button and when the user click on the button.. a dialog will open that display a list of image (image is another hildon.Button)

the problem is, when the image selected.. the image in the hildonButton previously (1st window) not updated.

how to update it like what happen on the calendars?

p/s: i am using pygtk

When the button in the pick color dialog is clicked, you need to emit a signal. Previous window needs to have that signal connected to a function that changes/updates the color in that button.

Don't forget that the signal emitted must have the picked color into brackets.

hi gionni88, thanks for the reply.

i did not understand what u mean, looking to the documentation, the only possible signal will be "pressed" & "released".

what do you mean?

You have to use custom signals. I don't know how to do that in pygtk, I'll explain how I do with c++ and qt. For an example look here: http://zetcode.com/tutorials/pygtktutorial/signals/

Let's say the pick color dialog is a child of the 1st window, you have to declare a custom signal in the pick dialog .h file and implement it in this way:

when the button is clicked (signal clicked), the dialog window emits the signal colorPicked(int color) where color is a number to distingue the several colors.

In the parent window file you connect that signal with a custom function that set the color variable and recolor/reload the updated color icon like this:
connect(dialog, SIGNAL(colorPicked(int)), parentWindow, SLOT(setColor(int));
