OpenDCL 7.0 is now officially released as a stable version after over 2 years of development and testing. The new release adds support for AutoCAD, Bricscad, and ZWCAD+ on Microsoft Windows, giving the growing number of lisp developers a user interface framework with the same cross platform support as their programming language.
Over the last few builds (alpha 3-5), there have been a number of new features that have been added to OpenDCL 5. Here is a quick recap if you haven’t been keeping up. Remember these new functions are still an Alpha work in progress, so make a backup before converting your existing projects. (Click on the thumbnail images below to see an enlarged version of them. Some are short videos showing the new stuff in action)
- Palette forms are now available.
- Here you’ll see how to insert the palette in the editor.
- Most controls have a new Drag & Drop framework that allows them to handle the Drag & Drop events without any Lisp code at all.
- Most controls now have a transparent background.
- Now you can import an image with a transparent background into a picture box. Set the background color of the image to 192,192,192, then set the picture box background to transparent.
- A new delay function has been added: (dcl_DelayedInvoke <delay as integer> <command-name as string>). This function executes a command after a set period of time (specified in milliseconds). If the command name starts with “c:”, it will call the lisp function with that name. It also runs in the background, so you can keep working in Acad while the timer is still running. Unlike (command “.DELAY”) where it freezes Acad & waits until the timer is done. This can be used for things like splash screens or other time-controlled activities, maybe a file system watcher or a chat application.
- Check boxes now support three states, and their ‘Value’ property is no longer a boolean, but an integer (0 = Unchecked, 1 = Checked, 2 = Indeterminate). Therefore, if you had code that checked whether a check box was checked via (if (dcl_Control_GetValue <control>) …), you’ll need to change this to (if (= 1 (dcl_Control_GetValue <control>)) …)
As Owen mentioned in his last post, OpenDCL 4.1 now supports Windows Visual Styles. So what’s that mean? As you’ve probably noticed, each major version of Windows comes with a new set of visual styles or themes (Win2000, XP,
The OpenDCL RC4 build has just been uploaded for everyone’s enjoyment. There where a few minor bug fixes, but the big news is it now has a built-in version checker. When you install OpenDCL Studio and load the runtime (ARX) module, it will automatically check to make sure it’s up-to-date & if it’s not, it will show you a balloon notification in the taskbar area. If you install the OpenDCL.runtime.msi it will not do this check automatically. You can do the check manually by calling the new function (dcl_UpdateCheck) or if you wish to enable the automatic version checking you can call the new function (dcl_SetAutoUpdateCheck <T/nil, otional>).
