MemObj GUI_button_img	(	MemObj *	o_par,
		char *	filnam,
		void *	funcnam,
		void *	data,
		int	hsiz,
		int	vsiz
	)

    create button with pixmap
    Input:
      o_par      parentBox
      filnam     image
      funcnam    callbackfunktion for the press-button-event
      data       get this data from the callbackfunktion; NULL for none
      siz        0   minimum size (size of caption)
                 1   maximum size (expand inside container)
                 >1  prepare size for <siz> nr of characters
                 <0  absolute size (in pixels)
     RetCod:     NULL = Error (filnam not exist)
   
    funcnam prototyp: 
      see GUI_button__ ()

int GUI_button_mod	(	MemObj *	mo,
		char *	ltext
	)

GUI_Butt_Label modify buttontext (caption)

MemObj GUI_Button__	(	MemObj *	o_par,
		char *	ltext,
		void *	funcnam,
		void *	data,
		char *	siz
	)

    Button.
    Input:
      o_par      parentBox
      ltext      caption (button-text)
      funcnam    callbackfunktion for the press-button-event
      data       get this (static) data from the callbackfunktion; NULL for none
    Output:
      gBut       must exist as long as button is alive.
    
    funcnam prototyp: 
      int funcnam (MemObj *mo, void **data);
      // data=table of 2 pointers;
      GUI_DATA_EVENT =*(int*)data[0]=TYP_EventPress
      GUI_DATA_I1=*(int*)data[1] or GUI_DATA_S1=(char*)data[1]  user-data
      GUI_OBJ_TYP(mo)  = TYP_GUI_Button
   
    Example with string-data:
    GUI_Butt__ (box0, "TestButton", UI_func1, "b1-clicked", 0, 0);
   
    int UI_func1 (MemObj *mo, void **data) {
        printf(" typ=%d\n",GUI_OBJ_TYP(mo));
        printf(" button |%s|\n", GUI_DATA_S1);
      ..
   
    Example with integer-data:
    static int icb = UI_FuncUCB1;
    GUI_Butt__ (box0, "TestButton", UI_func1, (void*)&icb, 0, 0);
   
    int UI_func1 (MemObj *mo, void **data) {
        if(GUI_DATA_EVENT == TYP_EventPress) {
          if(GUI_DATA_I1 == UI_FuncUCB1) {
            ..
   
    Disactivate:
      GUI_set_active (wButt, 0); //1=activ, 0=inaktiv
   
    Change text/caption/label:
      GUI_button_mod (wButt, " newText ");     // gtk_button_set_label

int GUI_button_press	(	void *	parent,
		MemObj	mo
	)

int GUI_ckbutt_get

(

MemObj *

mo

)

returns state of checkbox; 0=not sel, 1=selected.

int GUI_ckbutt_set	(	MemObj *	mo,
		int	mode
	)

    activate/disactivate Checkbox, Radiobutton.
    Input:
      mode    1 = TRUE  = ON
              0 = FALSE = OFF

MemObj GUI_ckbutt__	(	MemObj *	o_par,
		char *	ltxt,
		int	state,
		void *	funcnam,
		void *	data,
		char *	opts
	)

    Checkbox.
      o_par      parentBox
      ltext      caption (button-text)
      state:     0=FALSE: not checked; 1=TRUE: checked.
      funcnam    callbackfunktion for the press-button-event
      data       get this (static) data from the callbackfunktion; NULL for none
   
    funcnam prototyp:
      see GUI_button__ ()
   
    ---------------------------
    Example without callback:
   
      int istate;
      MemObj  cb1;
      // create checkbox
      cb1 = GUI_ckbutt__ (&box0, "ckb 1", TRUE, NULL, NULL, 0);
      // query state
      istate = GUI_ckbutt_get (&cb1)        // 0=not sel, 1=selected.
   
   
    ---------------------------
    Example with callback:
   
      GUI_ckbutt__ (&box0, "ckb 1", 0, f_ckButt_CB, NULL, 0);
   
    int f_ckButt_CB, (MemObj *parent, void **data) {
   
      if(GUI_ckbutt_get(parent)) goto L_activate;
      printf("f_ckbutt disactivate\n");
      ..
      L_activate:
      ..
    }
   
    ---------------------------
    Optional:
   
    activate with:
      GUI_ckbutt_set (&cb1, TRUE);
