drawing sentered text?!

[Diaboli]

I dont know if there is something about this out on the forum. i looked for it, but didnt find anything useful.

I need to display text that is sentered. for instance captions on buttons and names of players (wich needs to be directly overhead)

I had some code for this a while ago, but i managed to delete it...

hoping for help!

P.S: And i use UnDelphiX and Delphi 2006.

If the text drawing routines use the top-left for position, then all you need to do is this.

Calculate where you want the centre of the text to be. For a button,

CentreX := Button.Left + (Button.Width / 2);
CentreY := Button.Top + (Button.Height / 2);

Calculate the width and height of the text. I don't know DelphiX, so I'm not sure what the functions would actually be.

TextWidth := GetTextWidth(MyString);
TextHeight := GetTextHeight(MyString);

Now calculate where to draw the text.

TextX := CentreX - (TextWidth / 2);
TextY := CentreY - (TextHeight / 2);

And draw it. Again, replace the function with what DelphiX actually uses.

DrawText(MyString, TextX, TextY);

i cant see that UnDelphiX HAS a similar function as "GetTextWidth"..

anyone using UnDelphiX here that know this?

Set your canvas font size and name

then

DXDraw1.Surface.Canvas.TextOut(100-DXDraw1.Surface.Canvas.TextWidth('test'), 10, 'test');

Don't forget to release.
