Hi!
For a long time I was using code::blocks as IDE on ubuntu but now I decided to test Eclipse CDT. First of all I compiled a simple console application... no problem. Later I tried gtkmm and I compiled an application containing only an empty window... no problem so I decided everythig works. But it didn't I tried connecting a signal but it gives an error. Here is the signal:
Здравейте !
От доста време за програмиране използвамс редата code::blocks, но сега реших да пробвам Eclipse CDT. Първо компилирах едно просто конзолно приложение и нямаше проблеми. После компилирах проста програмка на gtkmm, която само показваше празен прозорец... пак нямаше проблеми, та затова реших, че всичко работи, но като се опитах да вържа сигнал не се получи. Ето сигнала:

Забелязах, че ако напиша sigc:: и натисна Ctrl + Space, Eclipse не завършва кода автоматично, а пътя съм го задал в настройките. Този проблем го нямам с namespace-овете Gtk или Glib. Пробвах с Cairo и Gdk, но и тях не ги разпознава въпреки, че съм им въвел пътя. Обаче проблеми с тях няма. Например този код се компилира без грешки:

Код:

sigc::signal<void, int> signal;
signal.emit(5);
Gdk::Color color;
Cairo::RefPtr<Cairo::Context> cairo;

Проблема е само когато вързвам сигналите и изаползвам sigc::ptr_fun или sigc::mem_fun. С други не съм пробвал и не знам дали има проблеми.

Edit: Оправих го... грешката беше моя... бях забравил да спомена, че наследявам Gtk::Window public и затова го наследяваше private. Като го оправих се компилира без проблеми
