Styled Text for Labels in your Xojo iOS app

If you like to get styled text on your labels in iOS, you can use our NSAttributedStringMBS class in our MBS Xojo MacCocoa Plugin like below.

As you see we create a NSMutableAttributedStringMBS object for some string and add attributes with zero based ranges there. We then use a declare to setAttributedText to assign the attributed string. Currently our classes for Cocoa controls are not ported to iOS in the plugin, but a quick declare helps us here.


EventHandler Sub Open() // create some text from a string. Could also read in RTF Dim a As NSAttributedStringMBS = NSAttributedStringMBS.attributedStringWithString("Hello World") // make a mutable copy Dim m As NSMutableAttributedStringMBS = a.mutableCopy // now add bold font Dim r1 As New NSRangeMBS(0,5) m.addAttribute(m.NSFontAttributeName, NSFontMBS.boldSystemFontOfSize(13), r1) // and underline Dim r2 As New NSRangeMBS(6,5) m.addAttribute(m.NSUnderlineStyleAttributeName, m.NSUnderlineStyleSingle, r2) // assign new styled text Declare Sub setAttributedText Lib "UIKit" Selector "setAttributedText:" (NSTextViewRef As ptr, AttributedStringHandle As Integer ) setAttributedText Label1.Handle, m.Handle End EventHandler

Not all styled are available on iOS. You can for example use NSForegroundColorAttributeName with NSColorMBS (actually UIColor on iOS internally) to color the text. Since superscript and subscript are not available, you can emulate it with using NSBaselineOffsetAttributeName to change the base line and then use a smaller font for the words.

DynaPDF with gradients in DeviceN colorspace

We got a new example for our MBS Xojo DynaPDF Plugin for using DynaPDFMBS class to create a gradient with DeviceN color space. We use DynaPDFExtGStateMBS to set the extended graphics state and enable overprint mode. Then we create the DevcieN colorspace based on a CMYK fallback. And within that colorspace we define an axial shading to get a gradient to fill an area in the PDF page. Here is the new sample code:

// Draw something in background so that we can see whether it works Call pdf.SetColorSpace(pdf.kcsDeviceCMYK) Call pdf.SetFillColor(PDF.CMYK(0, 0, 255, 0)) Call pdf.Rectangle(0.0, 0.0, 595.0, 842.0, pdf.kfmFill) Dim gs As New DynaPDFExtGStateMBS gs.OverPrintMode = 1 gs.OverPrintFill = 1 Dim gsHandle As Integer = pdf.CreateExtGState(gs) Call pdf.SetExtGState(gsHandle) // In this example, we emulate a CMYK color space with a DeviceN color space. // The required Postscript calculator function is super simple, it consists of only two braces"{}". Dim cls() As String = Array("Cyan", "Magenta", "Yellow", "Black") Dim cs As Integer = pdf.CreateDeviceNColorSpace(cls, "{}", pdf.kesDeviceCMYK, -1) Call pdf.SetExtFillColorSpace(cs) Dim sh As Integer = pdf.CreateAxialShading( 50.0, 50.0, 550.0, 50.0, 0.5, PDF.CMYK(60, 0, 0, 0), PDF.CMYK(255, 0, 0, 0), False, False) Call pdf.ApplyShading(sh)

This needs a DynaPDF Pro license from us for the plugin. Feel free to try the example project included with future MBS Plugin releases and send us questions.


Use text fields for numbers

Due to current events in an office nearby, here again an announcement announcement for all database developers:
Please treat the following numbers as text for processing and storing in a database.

Zip codes
While we call them zip numbers in Germany and they are just five digits here, a zip code may contain various other characters like letters, spaces and dashes. e.g. "SW1A 1AA" is a valid zip code in the United Kingdom. The length of post codes may be over 10 characters in some places and contain leading zeros. In Argentina even a plus may be used like "46C2+32".

Invoice Numbers
The number on an invoice, an offer or an order often has a scheme defined by the used software. Some companies use dashes to separate sections of the number like year-branch-number to give each shop branch their own running count for invoices. We have seen invoices numbers with prefix or postfix to indicate branches or types of invoices. (more)

The order of events in Xojo

When to initialize what is always a good question. Doing a custom constructor for Application, a Window or Control allows you to initialize some things before Xojo does some setup steps. For example if you like to have custom delegates for Cocoa frameworks, like our NSApplicationDelegateMBS class. The MBS Plugin registration can also either go into the constructor or App.Open event.

The constructor of a control allows you to do initialization steps before the control is added to the window. The open event of the control then allows you to do things after the control is initialized. And the open event of the window allows you to setup something after all controls are setup, e.g. connect a window splitter to the left and right controls. (more)
