In my previous article for PowerBuilder Developer's Journal (Vol. 18 issue
8), I gave a sneak preview of some of the things we were working on for PB15
Classic. This is a closer look at one of them - Tabs and Docking in MDI
Windows.
Recall that in the article we mentioned adding two new WindowType values -
mdidock! and mdidockhelp! - to the window object. Like values mdi! and
mdihelp!, respectively, they allow child windows (sheets) to be opened with
the OpenSheet functions. But these sheets will behave differently: they can
dock, float and be tabbed like the windows you see in our PB.NET IDE.
Your sheets will open docked by default (we will see how to control this
later in the article). Once opened, they can be moved, docked in much the
same way you can with the PB.NET IDE window. The sheets can be in one of four
states:
Tabbed Document: In PB.NET IDE, script edit... (more)
By the time you are reading this, PB12.5 will have been released and work on
PB15 well under way. A lot of exciting things have gone into the .NET version
of PB but we still get requests for features to go into the Classic version
of the product. Even though there was a lull in activity in PB12 Classic, we
are back again in 12.5 - and we are not stopping. You will probably have seen
Dave Fish's webcasts on plans for PB15 (his disclaimers apply here as well)
and are hungry for details - I hope to address that in this article.
PB has been around a long time and has accumulated many ... (more)
PowerBuilder 11 introduces the WebForms target, which lets you transform an
existing PowerBuilder application into a Web application with relative ease.
While the deployed application will be remarkably faithful to the original
client/server deployment in terms of application behavior, the degree of
faithfulness is limited by the fact that your application is running as a Web
application. The PowerBuilder component where this poses the greatest
challenge is the DataWindow.
The aim of this article is to point out where the transformed application
will differ in terms of latency, ... (more)
In PowerBuilder 11.5 we introduce features that allow you to easily give your
existing DataWindows a new look and feel. New properties are added to columns
and controls to allow you to add tooltips. You no longer have to settle for
single-colored backgrounds. We have introduced properties to control color
gradients and translucency for the background of columns, and most controls
and bands. For the DataWindow background, in addition to color gradients, you
can use bitmaps as wallpaper, giving you control over how the image is tiled.
Since these new properties are DataWindow prope... (more)
While there is literature describing how to use .NET controls in PB (see for
example, past issues of this magazine), all are silent on how to set control
properties at runtime and how to persist them. This article will address both
issues.
Like regular OLE controls, you can allow your .NET control properties to be
set at design-time by means of property pages (see Figure 1).
