Hi All,
I'm trying to use a pipe and execute a command such that the stdout from it is
displayed in a text display box. I've read Erco's tutorial on this but it is
unix based and this is for Win32.
The problem -as anyone would likely guess- is the failure to redraw the text
display in real-time. Instead the data is displayed after the command is
executed.
I've tried fiddling with Fl:check() to no avail. Anyways, some sample code is
below. This function is called with a command and then the results pipe out
into db_log which is a Fl_Text_Display object.
std::string NewProjectWindow::exec(char* cmd)
{
FILE* pipe = _popen(cmd, "r");
Fl_Text_Buffer *buff = new Fl_Text_Buffer();
if (!pipe)
return "ERROR";
char buffer[128];
std::string result = "";
while(!feof(pipe)) {
if(fgets(buffer, 128, pipe) != NULL)
{
result += buffer;
buff->text(result.c_str());
this->db_log->buffer(buff);
this->db_log->redraw();
Fl::check();
}
}
_pclose(pipe);
return result;
}
Any help/pointers are greatly appreciated. :)
