Function Documentation

MemObj GUI_button_img	(	MemObj *	o_par,
		char *	filnam,
		void *	funcnam,
		void *	data,
		char *	opts
	)

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
  opts       options; (HorSiz,VertSiz)
             HorSiz,VertSiz:  size in characters; default is automatic size.
                             'e' = expand widget; default is fixed size.
                              negative values: size in pixels.
             Examples: "" or "10" or "10e,e"
               "10e,e" horiz. size 10 chars, hor. and vert. expandable.

 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)

int GUI_button_styl	(	MemObj *	mo,
		int	iCol
	)

GUI_button_styl        modify buttonbackgroundColor
0=default; 1=red; 2=blue

MemObj GUI_button__	(	MemObj *	o_par,
		char *	ltext,
		void *	funcnam,
		void *	data,
		char *	opts
	)

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
  opts       options;  (HorSiz,VertSiz)
             HorSiz,VertSiz:  size in characters; default is automatic size.
                             'e' = expand widget; default is fixed size.
             Examples: "" or "10" or "10e,e"
               "10e,e" horiz. size 10 chars, hor. and vert. expandable.
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_button__ (box0, "TestButton", UI_func1, "b1-clicked", "");

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_button__ (box0, "TestButton", UI_func1, (void*)&icb, "");

int UI_func1 (MemObj *mo, void **data) {
    if(GUI_DATA_EVENT == TYP_EventPress) {
      if(GUI_DATA_I1 == UI_FuncUCB1) {
        ..

Disactivate:
  GUI_set_enable (&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

int GUI_ckbutt_set_noCB	(	MemObj *	mo,
		int	mode
	)

activate/disactivate Checkbox, Radiobutton but do not call userCB
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 select/deselect-event
  data       get this (static) data from the callbackfunktion; NULL for none
  opts       options; (HorSiz,VertSiz)
             HorSiz,VertSiz:  size in characters; default is automatic size.
                             'e' = expand widget; default is fixed size.
             Examples: "" or "10" or "10e,e"
               "10e,e" horiz. size 10 chars, hor. and vert. expandable.

funcnam prototyp:
  int funcnam (MemObj *mo, void **data); 
  // data=table of 2 pointers;
  GUI_DATA_EVENT =*(int*)data[0]=TYP_EventPress|TYP_EventRelease
  GUI_DATA_I1=*(int*)data[1] or GUI_DATA_S1=(char*)data[1]  user-data
  GUI_OBJ_TYP(mo)  = TYP_GUI_CheckBox

---------------------------
Example without callback:

  int istate;
  MemObj  cb1;
  // create checkbox
  cb1 = GUI_ckbutt__ (&box0, "ckb 1", TRUE, NULL, NULL, "");
  // 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, "");

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);
