Hi,

I'm using ResEdit to lay out my GUI. I'm having a bit of trouble getting my code right for setting a bitmap image in the GUI.

From what I understand, I have two options: a BitmapButton and a UserArea. I've tried both, but without much success. I was able to get an image in the GUI with a bitmapbutton, as long as I set it up in CreateLayout, but I'm not sure how to go about setting that up with my predefined BitmapButton from ResEdit.

I tried UserArea, as well, but by bitmap is not showing up. Here is the code I am trying for that:

//trying to set up bitmap preview
AutoAlloc<BaseBitmap> bmp;
bmp->Init(GeGetPluginPath()+Filename("res")+Filename("icon.tif"));
ua.DrawBitmap(bmp, 0, 0, 16, 16, 0, 0, 16, 16, BMP_NORMAL); //ua is a GeUserArea - public member of my GeDialog class
Bool UIAttached = AttachUserArea(ua, IDC_BITMAP_PREVIEW);
GePrint("UI Attached = " + BoolToString(UIAttached));

I get confirmation that the UserArea has been attached, but no bitmap shows up.

Any help here? I'd settle either for getting the bitmap button to work with the res file or getting the UserArea to work. I'm not too picky there

BitmapButton is the way to go programmatically. As far as I know, a predefined one never works.

I'd talk to Spanki (Riptide plugin developer) about using predefined UserArea with bitmaps (he seems to be doing this with Riptide). The URL to his site is:

Thanks. I'll send him a quick e-mail and see what he says. If I am not able to find a solution that works with my .res file, that means I'd have to ditch the .res file and code everything in the CreateLayout function, correct? There's no way that I can see to insert stuff in the middle of the layout, only before or after...

Just asking. A lot of work has already gone into the layout. I'd hate to have to recode it if I don't have to.

I'm not sure if this is the correct/proper way to do it, but this is how I got it to work...
I have a new class, based on a GeUserArea class... My header file (logo.h) :

    
    
    
    
    #include "c4d.h"
    
    
    
    
    class LogoBmp : public GeUserArea  
    {  
     private:  
    #ifdef _V7SDK_  
      BaseBitmap *m_pBmp;  
    #else  
      AutoAlloc<BaseBitmap> m_pBmp;  
    #endif  
     public:  
      Bool Logoname(char *szName);  
      virtual void Draw(LONG x1, LONG y1, LONG x2, LONG y2);  
    };

...the cpp file...

    
    
    
    
    #include "logo.h"
    
    
    
    
    Bool LogoBmp::Logoname(char *szName)  
    {  
    #ifdef _V7SDK_  
     m_pBmp = AllocBaseBitmap();  
    #endif  
     if( !m_pBmp || m_pBmp->Init(GeGetPluginPath()+String("res")+String(szName))!=IMAGE_OK )  
      return false;
    
    
    
    
     return true;  
    }
    
    
    
    
    void LogoBmp::Draw(LONG x1, LONG y1, LONG x2, LONG y2)  
    {  
     LONG wid, hgt;
    
    
    
    
     wid = x2-x1;  
     hgt = y2-y1;
    
    
    
    
     if( m_pBmp )  
      DrawBitmap(m_pBmp, x1, y1, wid, hgt, 0, 0, m_pBmp->GetBw(), m_pBmp->GetBh(), BMP_NORMALSCALED | BMP_ALLOWALPHA);  
    }

...then, in my case, I have 2 USERAREA s **** defined in my dialog's .res file...

    
    
    
    
    // C4D-DialogResource  
    DIALOG DLG_IMPFILE

...frankly, I no longer remember the particulars about how or why this works, but that's the way it's been in my code for years now :).

..oh, so yes - my bitmaps do not show up inside resedit - it shows placeholder bitmaps instead (it doesn't know the filenames, etc. that are in my code).

Thanks!

I ended up ditching the .res file and using a bitmap button. I was able to get the user area to work with the res file, but in the end, the code was more complicated than it needed to be with the user area.

About how/why the user area works, I figured out that, just like you have it, you have to set it up as its own class, and most importantly, you need to define the draw function in there that calls DrawBitmap().

The draw function gets called every time the user area needs to redraw, and it looks like that's the only place you can call DrawBitmap().
