But i have problem with button actions
.Some of my code:
//---- Header File----
class Button{
public:
//variables initiating like float x,y,z...
void func(void);
void draw(){
//Some drawing
}
void CheckButtonClick(float mx, float my,int key,int state){
if(mx >= x && mx <= x+w &&
my >= y && my <= y+h &&
state == 0 && key == 0){
click = true;
func();
}else
click = false;
}
};
//----Main File----
void AddButton(Button &button,string text,void func(),float x,float y,float z,float w,float h,float s,float r,float g,float b,GLuint tex,GLuint clicktex){
button.tex = tex;
button.clicktex = clicktex;
button.func() = func();
button.textsize = s;
button.text = text;
button.x = x;
button.y = y;
button.z = z;
button.w = w;
button.h = h;
button.color[0] = r;
button.color[1] = g;
button.color[2] = b;
}
Button button_file,
void close(){
exit(0);
}
void InitRendering(){
_buttondark = loadTexture ("Data/IvoGui/buttondark.tga");
_buttondark_click = loadTexture ("Data/IvoGui/buttondark_click.tga");
AddButton(button_help,"Pomoc",close(),133,5,0.001f,64,16,0.9f,1.0f,1.0f,1.0f,_buttondark,_buttondark_click);
}
It gives me an error:
invalid use of void expression
Without button actions everything works fine.
Can you help me with this actions?
Thanks in advance.
