| 1 | Wcl 2.02 is Now Available |
|---|
| 2 | ************************* |
|---|
| 3 | |
|---|
| 4 | A new update of Wcl is now available. Several minor changes have been |
|---|
| 5 | made to make Wcl easier to build on a wider range of platforms. |
|---|
| 6 | |
|---|
| 7 | Changes and New Capabilities: |
|---|
| 8 | |
|---|
| 9 | Methods! Callback procedures can now be "methods". The C++ method |
|---|
| 10 | naming convention is used, simply to avoid inventing a new syntax. |
|---|
| 11 | For example: |
|---|
| 12 | |
|---|
| 13 | *foo.callback: MailBox::DropFlag() |
|---|
| 14 | |
|---|
| 15 | The application can either let Wcl find the object related to a widget |
|---|
| 16 | or the application can provide a function which maps widgets and class |
|---|
| 17 | names to application objects. |
|---|
| 18 | |
|---|
| 19 | Dynamic Linking! It is now alot easier to dynamically bind callbacks |
|---|
| 20 | and/or methods from shared libraries on systems with dlopen and dlsym |
|---|
| 21 | (SVR4, SunOS, Solaris). |
|---|
| 22 | |
|---|
| 23 | Resource Visibility! You can more easily see what the hell is going |
|---|
| 24 | on inside the resource database. |
|---|
| 25 | |
|---|
| 26 | |
|---|
| 27 | What is Wcl? |
|---|
| 28 | ------------ |
|---|
| 29 | |
|---|
| 30 | Wcl is the Widget Creation Library. It allows all Look and Feel |
|---|
| 31 | aspects for an application to be specified in Xrm resource files, |
|---|
| 32 | leaving your application code to consist of a simple main() and |
|---|
| 33 | callback procedures. Wcl greatly reduces the learning curve for |
|---|
| 34 | developing applications with Widget based user interfaces, yet does not |
|---|
| 35 | restrict the developers to platforms, widget sets, nor development |
|---|
| 36 | languages. |
|---|
| 37 | |
|---|
| 38 | Wcl is widget set independent, but Xt Intrinsics dependent. Wcl can be |
|---|
| 39 | used on Xt Intrinsics from X11R3, Motif 1.0 (X11R3.5? as with SCO ODT), |
|---|
| 40 | X11R4, and X11R5. Some capabilities are not available on Xt Intrinsic |
|---|
| 41 | versions before X11R5. |
|---|
| 42 | |
|---|
| 43 | Wcl is portable: the distribution has been built and tested on |
|---|
| 44 | platforms with SVR3, SVR4, SunOS, and other varieties of UNIX. Some |
|---|
| 45 | embriotic support for VMS is also provided. Systems with dynamic |
|---|
| 46 | linking (SunOS and SVR4) which have dlopen() and dlsym() can also |
|---|
| 47 | invoke dynamically bound callbacks and actions from shared libraries. |
|---|
| 48 | |
|---|
| 49 | Support for Athena, Cornell, Motif, and OpenLook widgets are provided |
|---|
| 50 | with campanion libraries (widget set registration functions) and |
|---|
| 51 | resource interpreters with many example resource files. |
|---|
| 52 | |
|---|
| 53 | Wcl 2.02 will be distributed on comp.sources.x and source archive servers |
|---|
| 54 | including export.lcs.mit.edu |
