Wxwidgets Serial Port How To Do This

Wxwidgets Serial Port How To Do This

Both of them are used to execute the external programs and the sample shows how to do this synchronously (waiting until the program terminates) or asynchronously (notification will come later).

This overview aims at describing what each sample doesdemonstrates to make it easier to find the relevant one if a simple grep through all sources didnt help.

They also provide some notes about using the samples and what features of wxWidgets are they supposed to test.

It is organized in many different source files, one per each control, which makes it easier to study it, and also allows to change various control styles and call its methods interactively.

In this category you may find the following samples showing the corresponding controls.

When a foobar sample is mentioned below, its sources can be found in samplesfoobar directory of your wxWidgets tree.

This shows how to process ZIP and TAR archives using wxZipOutputStream and wxTarOutputStream.

It also shows how you can use wxArtProvider to get stock bitmaps for use in your application.

It shows how to configure the control (see the different options in the calendar menu) and also how to process the notifications from it.

On start up, it proposes to either crash itself (by dereferencing a NULL pointer) or generate debug report without doing it.

Next it initializes the debug report with standard information adding a custom file to it (just a timestamp) and allows to view the information gathered using wxDebugReportPreview.

These dialogs are described in detail in the Common Dialogs.

In the status bar, it displays the information gathered through its interface: in particular, the current connection status (online or offline) and whether the connection is permanent (in which case a string LAN appears in the third status bar field - but note that you may be on a LAN not connected to the Internet, in which case you will not see this) or not.

It is quite non trivial and may be safely used as a basis for implementing the clipboard and drag and drop operations in a real-life program.

On the top, there are two listboxes which show the standard derivations of wxDropTarget: wxTextDropTarget and wxFileDropTarget.

The last functionality available from the main frame is to paste a bitmap from the clipboard (or, in the case of the Windows version, also a metafile) - it will be shown in a new frame.

The more advanced features are demonstrated if you create a shape frame from the main frame menu.

A shape is a geometric object which has a position, size and color.

A shape object supports its own private wxDataFormat which means that you may cut and paste it or drag and drop (between one and the same or different shapes) from one sample instance to another (or the same).

However, chances are that no other program supports this format and so shapes can also be rendered as bitmaps which allows them to be pasteddropped in many other applications (and, under Windows, also as metafiles which are supported by most of Windows programs as well - try WriteWordpad, for example).

It shows how to dynamic events and connectingdisconnecting the event handlers during run time by using wxEvtHandler::Bind() and wxEvtHandler::Unbind(), and also how to use wxWindow::PushEventHandler() and wxWindow::PopEventHandler().

It doesnt do anything very exciting by itself, you need to study its code to understand what goes on.
