Goldenseal Pro Progress Report (Oct 24)

The Windows version of Goldenseal Pro is now caught up with the Mac version. Both show data entry layouts, load records, and move through them with the browser controls.

The Windows MFC library includes something called a combo box. It turned out to be perfect for our clairvoyant fields, which show a list of accounts (or whatever else) that goes into a field. You can click and choose from an alphabetical list, or start typing the first few letters until it jumps to the correct item.

Combo boxes also work for lists that doesn’t change (for example, status options or account classes). In the original Goldenseal, those are in a popup menu, which requires a mouse click. With the Windows combo box you can still do that, but you can also tab into the field, and type to choose. It makes data entry faster, since everything can be done from the keyboard.

When we wrote the Macintosh interface last winter, we used popup menus that require a mouse click, similar to Goldenseal 4.x. But, now that the Windows version works so much better, we will revisit that code and see if we can make it more similar.

Up until now, we have leap-frogged every 2 or 3 months between the Mac and Windows versions. As we move forward on one platform, we often discover improvements that apply to the other. We will continue to leap-frog, but on a faster cycle. The big stuff is out of the way, and the remaining tasks usually take days apiece, instead of months.

Programming for modern computers is turning out to be significantly easier than what we went through, during the 1990s. The libraries are more mature, and the hardware is more powerful. Back then, desktops typically had 4 megabytes of RAM, so we had to be very frugal about what we loaded into memory. Now that the norm is 4 gigabytes, life is much easier.

For example, in the current version of Goldenseal, we look up the data for popups and clairvoyant fields when we first load each record, so we know what text to display. But we don’t store the whole list, since it’s several hundred kilobytes of memory. When you click in a field, the list is retrieved a second time, to build the menu. It means a fraction of a second delay.

For Goldenseal Pro, it’s no big deal if we use an extra megabyte of RAM per record tab or window. Since we need to fetch the lists near the beginning anyhow, we might as well keep them around. That saves some milliseconds, if you click in the field later. We do have to worry about updating issues (what happens if you add an account?), but at least we have more options, now.

Next on the agenda: saving records, and the Find commands.
