Pixmaps

The XSTEP pixmap support enable you to use pixmaps in XPM format. Only 'type 1' pixmaps are supported, in a more correct language, you must reduce the number of pixmap colors.

#include "mozilla.xpm"

...

struct xtree *t;

...

mkpixmap(mozilla,t);
 

Load to X server pixmap and link to any XSTEP widget. Pixmaps can work with buttons, others widgets requires extra code to draw the pixmap.

#include <xstep.h>
#include "mozilla.xpm"

void draw(struct xtree *treeptr) {

        XCopyArea(display,treeptr->pix,treeptr->win,treeptr->gc,0,0,
                treeptr->wpix,treeptr->hpix,
                (treeptr->aw-treeptr->wpix)/2,(treeptr->ah-treeptr->hpix-14)/2);
}

void xmain(int n,char *p[]) {

        struct xtree *t;

        window_create(0,0,400,180,"box_create_xpm");

        t=box_create(8,8,64,64,draw,gray);
        mkpixmap(mozilla,t);

        button_create(-8,-8,72,24,"close",window_close);
}

In this small example, a window will be created with a box, a pixmap is created in the X server and linked to box widget. The callback function draw() copy the pixmap to the box in expose events.

#include <xstep.h>
#include "mozilla.xpm"

void xmain(int n,char *p[]) {

        struct xtree *t;

        window_create(0,0,400,180,"button_create");
        t=button_create( -8,-8,72,72,"close",window_close);
        mkpixmap(mozilla,t);
}

In this example, the pixmap is created in the X server and linked to a button widget, but isn't necessary any draw function (this is the only special case, all others widgets can't detect any pixmap, you must draw the pixmap in expose events).
