I had tried to do these,but it got the same result,:-(
My IDE: cw9, Palm Emulator 3.5, Win2k sp3.
I use LstSetDrawFunction() to draw list.
// draw list in frmOpenEvent:
lstP = (ListPtr) GetObjectPtr(MainCountryList);
LstSetDrawFunction(lstP, (ListDrawDataFuncPtr)MainListDrawFunc);
LstSetListChoices(lstP, NULL, 5);
static void MainListDrawFunc(UInt16 itemNum, RectanglePtr bounds, Char
**itemsText)
{
WinDrawChars(ListCountry[itemNum], StrLen(ListCountry[itemNum]),
bounds->topLeft.x, bounds->topLeft.y);
}
//ListCountry define:
Char ListCountry[5][10] =
{
{"China"},
{"England"},
{"France"},
{"Russian"},
{"American"}
};
