Window / Questions about handling a window

« on: January 17, 2018, 04:29:50 pm »

I looked through the documentation of sf::window and it seems to be impossible, but I'm asking just to be sure.

Is it possible to make a window which is resizable by grabbing its edge but which does not have a title bar? Also can I maximize or minimize or float the window from code?

General / Declaring sf::Font and sf::Color in a header

« on: January 15, 2018, 10:07:37 pm »

I needed a way to easily use same font and colors throughout my UI. Every UI component like button or textbox has its own class with render function. At first I made the fonts and colors as parameters of the render function but it seemed stupid to include them in every single one function call. Therefore I made a header which declares them:

#pragma once
#include <SFML\Graphics.hpp>

extern sf::Color baseColor;
extern sf::Color darkAccent;
extern sf::Color lightAccent;
extern sf::Color colorAccent;

extern sf::Font baseUiFont;

The header is included in every .cpp file that needs the variables.

Then I define them in the beginning of my main() like so:

sf::Color baseColor(50, 50, 50);
sf::Color darkAccent(30, 30, 30);
sf::Color lighAccent(70, 70, 70);
sf::Color colorAccent(255, 140, 0);

sf::Font baseUiFont;
baseUiFont.loadFromFile("Resources/OpenSans-Regular.ttf");

The problem is that this does not work. I get two errors:

Error   LNK2001 unresolved external symbol "class sf::Color baseColor" (?baseColor@@3VColor@sf@@A)
Error   LNK1120 1 unresolved externals

I tested similar declaration and definition of a simple int variable and it did work. Therefore I think that the problem is in the way SFML works. Is there a solution to this? All I need is a simple way to pass these variables to every object that needs them.
