How to get regular + unicode character as button text (Winforms )

ic2 · Post by **ic2** » Tue Feb 21, 2023 8:33 pm

I want Ctrl and then (on the next line) an arrow symbol as button text (Winforms ).

I tried

Self:MyButton:Text:="Ctrl"+crlf+"u2192"

(After seeing a C# question answered by: button1.Text = "Hello u2129" ;
but I get the literal text u2192 on the next line

How can I solve that?

Hi Dick,

In c#, by default literal strings use escape sequences (special embedded codes starting with a ""), while in X# this is off by default. In order to specify that the a literal string should use such escape sequences, you must prefix it with "e". And since "r" standsfor LF and "n" for CR, you'd need to use

Code: Select all

Self:MyButton:Text := e"Ctrlrnu2129"

But I think showing an arrow this way is a bit ugly. Why don't you use and put a normal arrow bitmap on the button, together with the normal caption? In WinForms, it's a lot easier and more convenient to put an image on a button, in any way you like it, than it was in VO.

FTR, i think it is the other way round

Splendid!
It also answers a question I had earlier: what is the meaning of the "e" I saw in some ILSpy converted code. Thanks for that.
Small remark: you wrote '2129' (the right arrow is is 2192)

On the contrary. It looks exactly how it should look; adding a bitmap together with a text (Ctrl) often make it look a bit out of proportions. Besides: this is one line of code instead of having to first create a bitmap, add it somewhere, use it. If a font has a clear and meaningful symbol for something I prefer that much above using a bitmap.
