Function Documentation

MemObj GUI_menu_radiobutt__ ( MemObj o_par,
char *  ltxt,
int  ii,
void *  funcnam,
void *  data 
)
Radiobuttons.
The callbackfunctions provides signal "activated" and "disactivated"
Input:
o_par parentBox
ii 0=start new radioButtonChain; 1=add button to existing chain
ltxt caption
funcnam callback-function or NULL; returns data of selected RB
data this data will be provided by the callback-function
funcnam prototyp:
int funcnam (void *parent, void **data);
// data=table of 2 pointers;
GUI_DATA_EVENT =*(int*)data[0]=TYP_EventPress|TYP_EventRelease
GUI_DATA_I1=*(int*)data[2] or GUI_DATA_S1=(char*)data[2] user-data
Example:
GUI_menu_radiobutt__ (&box0, "button1", 0, cb_rb1, (void*)"rb1", 0);
GUI_menu_radiobutt__ (&box0, "button2", 1, cb_rb1, (void*)"rb2", 0);
GUI_menu_radiobutt__ (&box0, "button3", 1, cb_rb1, (void*)"rb3", 0);
int cb_rb1 (void *parent, void **data) {
// skip disactivation
if(GUI_DATA_EVENT == TYP_EventRelease) return 0;
printf(" being activated: |%s|\n",GUI_DATA_S1;
}
int GUI_menu_radiobutt_get ( MemObj mo)

test a menu-radiobutton if it is active. 1=active, 0=not active.

void GUI_menu_radiobutt_set ( MemObj mo)

set a menu-radiobutton to state = active.

int GUI_menu_checkbox_get ( MemObj mo)

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

int GUI_menu_checkbox_set ( MemObj mo,
int  mode 
)
activate/disactivate menu-Checkbox, Radiobutton.
Input:
mode 1 = TRUE = ON
0 = FALSE = OFF
MemObj GUI_menu_checkbox__ ( MemObj o_par,
char *  ltxt,
int  state,
void *  funcnam,
void *  data 
)
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 data from the callbackfunktion; NULL for none
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
---------------------------
Example without callback:
int istate;
MemObj cb1;
cb1 = GUI_menu_checkbox__ (&men1, "ckb 1", 0, NULL, NULL);
// query state
istate = GUI_menu_checkbox_get (&cb1) // 0=not sel, 1=selected.
---------------------------
Example with callback:
GUI_menu_checkbox__ (&men1, "ckb 1", 0, mywin3, (void*)"cb1");
int mywin3, (MemObj *parent, void **data) {
if(GUI_DATA_EVENT == TYP_EventPress) {
if(!strcmp(GUI_DATA_S1, "cb1")) {
..
---------------------------
Optional:
activate with:
GUI_menu_checkbox_set (&cb1, TRUE);
MemObj GUI_menu__ ( MemObj o_par,
char *  ltxt,
int  mode 
)
GUI_Menu__ create menu or submenu
Input:
o_par parentbox or parent-menushell
ltxt menu-title, NULL for creating the menu-bar
mode 0=normal; 'r'=right-justified; 's'=Submenu.
1 (ltxt=NULL only) expand inside parent-container
Example:
MemObj menu_bar, men_fil, mns, men_hlp, wm2, wml;
menu_bar = GUI_menu__ (&box1, NULL, 0); // create Menubar
men_fil = GUI_menu__ (&menu_bar, "File ", 0); // first Menu on Menubar
men_hlp = GUI_Menu__ (&menu_bar, "Help ", 'r'); // Menu rechts
GUI_menu_entry (men_fil, "New", UI_CB, (void*)"new"); // add entry to Menu
mns = GUI_menu__ (&men_fil, "Save as ", 0); // add submenu
GUI_menu_entry (&mns, "dxf", UI_CB, (void*)"saveDxf");
GUI_menu_entry (&men_fil, "---", NULL, NULL); // menu-separatorline
GUI_menu_checkbox__ (&men_fil, "wmcb1", 0, UI_CB, (void*)"wmcb1");
wm2 = GUI_menu__ (&menu_bar, "Lang ", 'r');
GUI_menu_radiobutt__ (&wm2, "de", 0, mywin3, "l-de", 0);
wml = GUI_menu_radiobutt__ (&wm2, "en", 1, mywin3, "l-en", 0);
GUI_menu_radiobutt_set (&wml); // preset en
int UI_CB (MemObj *mo, void **data) {
printf("UI_CB %d\n",GUI_DATA_EVENT);
if(GUI_DATA_EVENT == TYP_EventPress) {
if(!strcmp(GUI_DATA_S1, "new")) {
..
MemObj GUI_menu_entry ( MemObj o_par,
char *  ltxt,
void *  funcnam,
void *  data 
)
create menuItem or MenuSeparator (if ltxt == "---")
Input:
o_par parentBox
ltxt item-text
funcnam callback from selection
data get this data from the callbackfunktion; NULL for none
funcnam prototype:
int funcnam (void *parent, void **data);
// data=table of 2 pointers;
GUI_DATA_EVENT =*(int*)data[0]=TYP_EventPress
GUI_DATA_I1=*(int*)data[2] or GUI_DATA_S1=(char*)data[2] user-data
RetCod: gio_typ = TYP_GUI_OptMen
