[paragui-dev] PG_Font Bug Clarification

[Mark Krosky]

Here is a minimal example that reproduces the bug:

- start with tut1.cpp from the documentation

Under 
#include "pgapplication.h" 
Add 
#include <pgfont.h> 
Over 
app.Run(); 
Add 
PG_Font font("font.ttf");
It compiles, but does not link. 
Problem: link error, because PG_Font constructor and destructor are not
found.
It looks like PG_Font is not appropriately defined in the library.

[I have my compiler recognizing the paragui headers as part of the
standard include path; you'll need to change the <> to ""
if you haven't done that.]

[More details below]

: What kind of error ? Where is the exact location of the error in
the code ?

I was getting both a link error and a compile error.

I had to include the struct
struct PG_FontDataInternal {

        

SDL_Color
color;

        

int
alpha;

        

int
style;

        

int
size;

        

int
index;

        

std::string
name;

        

Uint32
dummy1;

        

Uint32
dummy2;

        

PG_FontFaceCacheItem*
FaceCache;

};

in my header somewhere in order to get things to compile.
[This struct was not used in my code, but it was used and undeclared in
the ParaGUI headers.]

I manually included the PG_Font constructor and destructor in order to
get it to link.

PG_Font::PG_Font(const char* fontfile, int size, int index) {

        

my_internaldata
= new PG_FontDataInternal;

        

my_internaldata->FaceCache
= NULL;

        

my_internaldata->name
= fontfile;

        

my_internaldata->size
= size;

        

my_internaldata->index
= index;

        

my_internaldata->color.r
= 255;

        

my_internaldata->color.g
= 255;

        

my_internaldata->color.b
= 255;

        

my_internaldata->alpha
= 255;

        

my_internaldata->style
= 0;

        

my_internaldata->FaceCache
= PG_FontEngine::LoadFontFace(fontfile, size, index);

        

        

if(my_internaldata->FaceCache
== NULL) {

        

        

PG_LogERR("Unable
to create font (name=\"%s\", size=\"%i\",
index=\"%i\"", fontfile, size, index);

        

}
}

PG_Font::~PG_Font() {

        

delete
my_internaldata;
}

: Which part did you modify to get it working ? 

I put in the above 2 segments.  I also had problems with the
headers
#include <pglog.h>
#include <facecache.h>

I think that facecache.h is in a different directory from the other
headers, which causes problems.

: Did you specify the subdir where the font file is located ? Alex

Why do I need to do that?  In simple.zip, everything is located in
the same directory?  Are you saying that I need to do
"simple\font.ttf" rather than "font.ttf"?  I
thought that once I specify the "simple" theme, it
automatically knows where to look?
