I am just starting to port some programs to fpc using Lazarus form
Tcl/Tk. I have some questions about things I can do fairly easily in
Tcl/Tk which I am not sure how to achieve in fpc/lazarus. At present I
only need Linux specific answers.
1. I am connecting to an external microcontoller development board by
a serial interface. I need to be able to set this interface non
blocking. I can see how to open the serial interface using the serial
unit but it is not clear how to set it non blocking.
2. I need to respond to the occurence of input on the serial port.
This is trivial in Tcl - fileevent FileDescriptor FunctionName - how
do I achieve this in fpc?
3. In Tcl/Tk I use a textarea widget with keyboard entry disabled to
show progress and data. The nearest equivalent in LCL seems to be
TMemo. How do I disable keyboard input to this and where can I find
documentation on this and other) components - the wiki seems fairly
silent on this or do I just assume it work like a Delphi TMemo?
Any help will be appreciated.
Ian
