Okay... I'll have to get back to you on the disable panelbars option, and the
following code has a small memory leak (It's a bug in the server or client lib) but
the following code should point you in the right direction.
PicoGUI's contexts are a lot like variable scopes in C, and help to eliminate big
chunks of unneeded memory. They work like a stack, and can be nested practically
indefinitely.
Also note that this uses a new feature, toggle buttons, so update and recompile your
server and client lib

#include <picogui.h>
int btnLaunchPanel(struct pgEvent *evt) {
if (pgGetWidget(evt->from,PG_WP_ON)) {
/* Make panel */
pgEnterContext();
pgRegisterApp(PG_APP_NORMAL,"Finder Panel",0);
/* Your Panel Here :)
* If you want a button grid, take a look at the "calculator" demo
*/
pgNewWidget(PG_WIDGET_LABEL,0,0);
pgSetWidget(PGDEFAULT,
PG_WP_TEXT,pgNewString("Hello,\nWorld!"),
PG_WP_SIDE,PG_S_ALL,
PG_WP_FONT,pgNewFont(NULL,25,PG_FSTYLE_BOLD),
0);
}
else
/* Destroy panel */
pgLeaveContext();
return 0;
}
int btnExit(struct pgEvent *evt) {
exit(0);
}
int main(int argc, char **argv) {
pgInit(argc,argv);
pgRegisterApp(PG_APP_TOOLBAR,"Finder Toolbar",0);
pgNewWidget(PG_WIDGET_BUTTON,0,0);
pgSetWidget(PGDEFAULT,
PG_WP_TEXT,pgNewString("Panel"),
PG_WP_EXTDEVENTS,PG_EXEV_TOGGLE, /* Use new toggle button! */
0);
pgBind(PGDEFAULT,PG_WE_ACTIVATE,&btnLaunchPanel,NULL);
pgNewWidget(PG_WIDGET_BUTTON,0,0);
pgSetWidget(PGDEFAULT,
PG_WP_TEXT,pgNewString("X"),
PG_WP_SIDE,PG_S_RIGHT,
0);
pgBind(PGDEFAULT,PG_WE_ACTIVATE,&btnExit,NULL);
pgNewWidget(PG_WIDGET_LABEL,0,0);
pgSetWidget(PGDEFAULT,
PG_WP_TEXT,pgNewString("Panel Launcher Test"),
PG_WP_SIDE,PG_S_LEFT,
0);
pgEventLoop();
return 0;
}
