    <p>I have a class that manages a SDL_Surface for me, and I want to make it so that I don't have to worry about freeing the surface. I have this code so far:</p> <pre><code>//In Entity.h class Entity { public: int x, y, width, height; Entity(std::string); ~Entity(); void render(); private: SDL_Surface* texture; }; //In Entity.cpp Entity::~Entity() { printf("Destroying an Entity"); SDL_FreeSurface(texture); } //In main.cpp Entity puppy("puppy.bmp"); void render() { clearScreen(); puppy.render(); } int main (int argc, char **argv) { printf("started"); init(); bool done = false; while(!done) { ... // Draw the screen printf("About to render"); render(); SDL_Flip(screen); } SDL_Quit(); return 0; } </code></pre> <p>When I run it, I get <code>Program received signal EXC_BAD_ACCESS, Could not access memory. Reason: KERN_INVALID_ADDRESS at address: 0x0000000000000260 0x000000010002fd9b in SDL_DisplayFormat ()</code> Am I correct in assuming that the destructor is getting called early and it's trying to render a NULL texture? The code works fine if I don't have the destructor and just waste memory. I've also tried it with puppy being a local variable and passing it to render, but that doesn't help.</p> <p>EDIT: The code runs for only a second, then crashes. It doesn't wait to exit the loop. Also, stepping through the program with gdb reveals the puppy to be drawn at least once for some reason.

    1. COYou don't seem to be doing any of the SDL initialization.

    2. COThis doesn't look like your code, because that wouldn't even compile (or link, for that matter). In _your_ code, are you sure no copies of `Entity` are made?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
