### 10.9 Object Specific Attributes

Many objects have attributes that are specific to its object class, such as slider bounds, precision etc. You can access these attributes (if existent) via the tab rider labeled "Spec". In most cases the meaning of these attributes hopefully is self-explanatory (otherwise see the detailed description of the different object classes in Part III) and all changes made are shown immediately so you can see what effects the changes have on the object. Once satisfactory results have been achieved the press button labeled "Accept" to accept the settings (clicking on the tab rider "Generic" has the same effect). Two additional buttons, "Cancel" and "Restore", are available to cancel the changes (and quit the attribute settings form) and restore the defaults, respectively.

One particular aspect of the pixmap/bitmap button initialization needs a little more explanation as the setting of button labeled "Use data" has no effect on the appearance of the button in fdesign but nonetheless affects the generated code. By default, the "Use data" button is off, indicating the pixmap/bitmap file specified is to be loaded dynamically at run time via `fl_set_pixmapbutton_file()` (or the bitmap counterpart function). If "Use data" is on, the specified file and its associated data will be `#include`’d at compile time so the data becomes part of the code. Depending on the application setup, you may choose one method over the other. In general, including the data in the code will make the code slightly larger, but it avoids problems with finding the specified file at runtime. The button labeled "Full Path" only applies if "Use Data" is on. If "Full Path" is also on, the pixmap file will be `#include`’d using the full path, otherwise only the filename is used, presumably the compile process will take care of the path via the `-I` flag in some system dependent way.
