EKB 2005-07-08:
I have now
Snitified this package. The code samples have been replaced with the new Snit versions.''
I've been working towards making a package that will automatically take care of some tricks for using
Tk under
Windows that I learned once and don't want to have to learn again. For example:
- Binding the "x" button to the exit procedure
- Linking to an .ico file
- Creating a resizer/gripper in the bottom-right corner (using code from the sizer control page on this Wiki)
- Creating tooltips (also known as balloon help) using the code from the Snit Tooltips page
- Creating a toolbar and finding button images for it (I embedded some inline images, but you might want to use ICONS instead!)
- Adding a status bar, and connecting it to the toolbar buttons
- Saving preferences in the user's directory
- ... and so on ...
I've put some of these things together into a simple application framework. It uses some of my own code, as well as code from other pages on the Tcler's Wiki and the web. (These are documented in the code.)
Here's an example of an application created using the Application Framework code (This is actually the program I used to create the base64-encoded button strings that appear in the Framework, so it is hopefully useful by itself.)
To use the "Transparent Color" feature in the program, first fill any areas in the image that you want to make transparent with some color, for example, pure green (R = 0, G = 255, B = 0). Then type those numbers into the R, G, B entry widgets. When the image is loaded, any pixels that are set to (0,255,0) will be made transparent. The screenshot above shows this image loaded in the program:
.
And here's the code to make the example, using the Application Framework (which is farther down on the page) A couple of things to notice in the code:
- Any values assigned to the "globalPrefs" array or set using the "myapp setpref" method are automatically saved on exit and retrieved when the program is restarted
- Balloon help is available for all widgets, including toolbar buttons

Framework edit
Here's the framework as it currently stands (last modified 8 July 2005). It includes a lot of embedded image data with standard button images (open, save, etc.) -- use [WinApp::buttonlist] to see the pre-defined images.
