The t beta for Windows is available at: http://www.jsoftware.com/download/j601tbeta_win.exe
This beta includes some updates to the scripts, but the main changes are in Jwdw and Jwdp to respond to suggestions from Oleg and others on isigraph behaviour, especially with multiple controls on a form.
1. Jwdw and Jwdp - all wdhandler events for an isigraph control (focus, focuslost, paint, print, char, wheel, mouse) automatically do a glsel for the control.
2. wd setinvalid now works in both Jwdw and Jwdp and if done to an isigraph the pixel buffer is cleared so that a paint event will be triggered. Previously setinvalid was not supported in Jwdp and in Jwdw it didn't clear the buffer so the requested paint was usually done by just copying the buffer to the screen without triggering a paint event.
3. wheel events require keyboard focus. This is part of the problem shown by Oleg's example with two grids on form. The tab key can be used to shift focus between the controls and the wheel event is triggered to the control with keyboard focus. Note that char events such as up/down arrow go to the same grid as the wheel events. The gird code needs to be updated to do appropriate setfocus and this will be done for the next beta.
