| 1 | Widget Creation Library Version 2.7 Distribution |
|---|
| 2 | ------------------------------------------------ |
|---|
| 3 | |
|---|
| 4 | The distribution contains files which make up the Widget Creation |
|---|
| 5 | Library (Wcl or libWc.a), and resource interpreters and utility |
|---|
| 6 | libraries (which include Table widgets) for each of the following |
|---|
| 7 | widget sets: Athena, Motif, and OpenLook. |
|---|
| 8 | |
|---|
| 9 | Wcl is completely widget set independent. It provides mechanisms to |
|---|
| 10 | allow an entire user interface to be specified in resource files. |
|---|
| 11 | Basically, this amounts to providing new resources for specifying the |
|---|
| 12 | types of the widgets and the widget heirarchy. In addition, Wcl |
|---|
| 13 | provides several callbacks and action functions which many programs |
|---|
| 14 | need. |
|---|
| 15 | |
|---|
| 16 | See README20 for general information about Wcl version 2, and README22 |
|---|
| 17 | for additional features introduced in Wcl version 2.2 and version 2.1, |
|---|
| 18 | and README23 for new features in Wcl 2.3, README24 for new features in |
|---|
| 19 | Wcl 2.4, README25 for new features in Wcl 2.5, and README26 for new |
