I'm trying to make a gui which has a SimpleWindow class that contains a textPanel class:
class textPanel{
private:
std::string text_m;
public:
textPanel(std::string str):text_m(str){}
~textPanel();
};
class SimpleWindow{
public:
SimpleWindow();
~SimpleWindow();
textPanel text_panel_m;
};
SimpleWindow::SimpleWindow():
text_panel_m(std::string temp("default value"))
{
}
I want to be able to initialize the text_panel_m using a const char* that gets converted to a std::string without needing to make another constructor that takes a const char*. Should I just create another constructor with const char* as an argument anyway? If I do it this way is there a way to reduce the amount of redundant constructor code using c++0x?
With the approach above I'm having difficulties initializing the text_panel_m member variable. g++ gives me the following error:
simpleWindow.cpp:49: error: expected primary-expression before ‘temp’
simpleWindow.cpp: In member function ‘bool SimpleWindow::drawText(std::string)’:
How do I go about initializing the text_panel_m member variable without using the default constructor?

You're almost there:
Should do the trick, using
std::string
's implicit converting constructor fromconst char*
.
