| 28 | <h4>Problems</H4> |
|---|
| 29 | EXPGUI (and soon CMPR) is distributed with a version of Tcl/Tk |
|---|
| 30 | that includes the Tkcon, BWidget and BLT packages included within the Tcl/Tk |
|---|
| 31 | executable. The Bwidget package is required for EXPGUI (someday the |
|---|
| 32 | same for CMPR). The BLT package is required for CMPR and is needed by all the |
|---|
| 33 | graphics routines in EXPGUI. The Tkcon package is optional. |
|---|
| 34 | EXPGUI includes the La (Linear algebra) package for use in the BKGFIT |
|---|
| 35 | routine. |
|---|
| 36 | <P> |
|---|
| 37 | If you are not using the version of Tcl/Tk packaged with the program, |
|---|
| 38 | perhaps because you want to use them on a platform other than the |
|---|
| 39 | ones supported by me, you will need to confirm that these packages |
|---|
| 40 | work properly. |
|---|
| 41 | You can test if Tcl/Tk and the BLT package are installed correctly using the |
|---|
| 42 | following unix commands: |
|---|
| 43 | (In Windows, instead double-click on the appropriate icon.) |
|---|
| 44 | <PRE> |
|---|
| 45 | [d120234:~] toby% wish |
|---|
| 46 | % package require BLT |
|---|
| 47 | 2.4 |
|---|
| 48 | % pack [blt::graph .g] |
|---|
| 49 | % Blt_ZoomStack .g |
|---|
| 50 | % exit |
|---|
| 51 | </PRE> |
|---|
| 52 | When you type "wish" and press Enter, a new small blank window should appear. |
|---|
| 53 | when you type the 2nd line, "package require BLT," there will be no change in |
|---|
| 54 | the blank window, but the computer should respond "2.4". After the |
|---|
| 55 | "pack [blt::graph .g]" command is entered, a set of x- and y-axes should appear |
|---|
| 56 | in this window. After the Blt_ZoomStack command is typed the plot should "zoom" with the mouse. |
|---|
| 57 | |
|---|
| 58 | The window should disappear after "exit" is typed. |
|---|
| 59 | |
|---|
| 60 | Problems: |
|---|
| 61 | <OL> |
|---|
| 62 | <LI> If wish does not work, then Tcl/Tk is not installed or is not found in the path |
|---|
| 63 | |
|---|
| 64 | <LI> if the package require command is not working then BLT is not loaded or is not found by Tcl/Tk |
|---|
| 65 | |
|---|
| 66 | <LI> if the pack command does not work, you probably mistyped it (assuming that 1 & 2 worked OK) |
|---|
| 67 | |
|---|
| 68 | <LI> if the Blt_ZoomStack command does not work, then BLT is not finding the support file bltGraph.tcl. |
|---|
| 69 | This is usually found by looking for a subdirectory named .../blt2.4/ |
|---|
| 70 | in one of the directories referenced by tcl variable auto_path; this command |
|---|
| 71 | causes file .../blt2.4/pkgIndex.tcl to be loaded which references the libBLT.so |
|---|
| 72 | file (for example) and the bltGraph.tcl file. |
|---|
| 73 | </OL> |
|---|
| 74 | <P> |
|---|
| 75 | Likewise, this command should work for BWidget: |
|---|
| 76 | <PRE> |
|---|
| 77 | [d120234:~] toby% wish |
|---|
| 78 | % package require BWidget |
|---|
| 79 | 1.6 |
|---|
| 80 | % exit |
|---|
| 81 | </PRE> |
|---|
| 82 | Note that EXPGUI and CMPR have not been tested with BWidget versions later |
|---|
| 83 | than 1.6. |
