int GUI_entry_styl	(	MemObj *	o_par,
		int	imod
	)

GUI_entry_styl    modify frame of entry;
imod      0=GUI_STYL_normal=default_frame;  1=GUI_STYL_activ=red_frame.

int GUI_entry_pos_get

(

MemObj *

o_par

)

GUI_entry_pos_get   get cursorPosition
retCod = position; 0=leftmost.

int GUI_entry_pos_set	(	int	cPos,
		MemObj *	o_par
	)

GUI_entry_pos_set set cursorPosition cPos -1 = last pos.

int GUI_entry_copy	(	char *	cbuf,
		int	sSiz,
		MemObj *	mo
	)

GUI_Entry_Get get text from entryField - copy
sSiz    size of cbuf

char* GUI_entry_get

(

MemObj *

mo

)

GUI_entry_get get text from entryField - get pointer

int GUI_entry_set	(	MemObj *	mo,
		char *	text
	)

set text in entryField

MemObj GUI_entry__	(	MemObj *	o_par,
		char *	ltxt,
		char *	etxt,
		void *	funcnam,
		void *	data,
		char *	opts
	)

Create text-inputfiled. Gtk-2: siza cannot be smaller than ~10 characters ..

  ltxt:      Labeltext; NULL or "" for none
  etxt:      Text in Entryfield; NULL oder "" for none
  funcnam:   callback-function for Keypress & FocusIn-Events (none: NULL)
  data       get this (static) data from the callbackfunktion; NULL for none
  opts       options;  must have correct sequence (Frame Side HorSiz VertSiz)
             Frame: 'f' make a frameless inputfield; default = with frame.
             Side:  'r' labeltext is right of inputfield; default is left.
             HorSiz,VertSiz:  size in characters; default is automatic size. 
                             'e' = expand widget; default is fixed size.
             Examples: "f,20" or "r" or "r,10" or "10e,e"
               "r"     label right of inputfield; defaults.
               "r,10"  label right, horiz. size 10 chars, vert. size autom.
               "10e,e" horiz. size 10 chars, hor. and vert. expandable.

prototyp funcnam:
int funcnam (MemObj *mo, void **data); 
  // data=table of 4 pointers;
  GUI_DATA_EVENT =*(int*)data[0]=TYP_EventEnter|
                                 TYP_EventPress|
                                 TYP_EventRelease
  GUI_DATA_S1    =(char*)data[1]=userdata
  GUI_DATA_I2    =*(int*)data[2]=keyvalue; eg 'a'
  GUI_DATA_I3    =*(int*)data[3]=state of modifierkeys;
                                 see ../gui/gui_types.h  GUI_Modif_*
                                 &1=shift; &4=ctrl; &8=alt.
                                 &256=MB1; &512=MB2; &1024=MB3.
  GUI_OBJ_TYP(mo)  = TYP_GUI_Entry
  Returncodes:    0=continue with defaultOperations for this key.
                  1=do no defaultOperations; skip handling this key

Example without callback-function:
  we1 = GUI_entry__ (&box1, "0.0", "sum", NULL, NULL, "");

  printf(" |%s|\n",GUI_entry_get(&we1));

Example with callback-function:
  we2 = GUI_entry__ (&box1, "0.0", "sum", went_cb, NULL, "10");
  ..
  int we2_cb (MemObj *mo, void **data) {
    printf(" event=%d typ=%d\n",GUI_DATA_EVENT,GUI_OBJ_TYP(mo));
    if(GUI_DATA_I2 == GUI_KeyCurDown) return 1;       // skip handling
    if(GUI_DATA_EVENT != TYP_EventRelease) return 0;  // continue normal
    printf(" |%s|\n",GUI_entry_get(mo));
    ..
  }

int GUI_entry_cb	(	void *	parent,
		void *	event,
		MemObj	mo
	)

INTERNAL
returns 0=event   TYP_EventEnter|TYP_EventRelease
        1=userdata
        2=key
        3=modfier

int GUI_entry_sel_del

(

MemObj *

mo

)

GUI_entry_sel_del      clear selected text
if inputfiled has selected text, remove this selection.
