| Post subject: | PxLenght of Text in String/TextGadget |
Hi, is there a way to determine the length (in pixels- not characters) of a text to be displayed in a StringGadget or TextGadget? I want to display text of varying lengths in deactivated StringGadgets. Long Texts should be displayed in MultiLine Gadgets, short text in single lines to save space. Problem is, i dunno how to find out the number of lines i need for a given text. thanx, Searhin |

Code: Procedure TextWidth(text$)
GetTextExtentPoint32_(GetDC_(0), text$, Len(text$), sz.SIZE) ProcedureReturn sz\cx EndProcedure |

Have in mind that it gives width for text with the default GUI font. If you change font, you should use this (after UseFont() or SetGadgetFont()): Code: Procedure TextWidth(text$, WindowID)
hDC = GetDC_(WindowID) GetTextExtentPoint32_(hDC, text$, Len(text$), sz.SIZE) ReleaseDC_(WindowID, hDC) ProcedureReturn sz\cx EndProcedure |

None API based one: Code: If StartDrawing(WindowOutput())
Length = TextLength("Hahah") StopDrawing() EndIf |

> A TextHeight(text$) - function would be nice. Try this: http://forums.purebasic.com/english/vie ... php?t=3801 Not sure if it does what you want, but the value of "tm\tmHeight" that it returns might be the height of the text. Give it a try... |

This works with height, too: Code: Procedure TextHeight(text$, WindowID) hDC = GetDC_(WindowID) GetTextExtentPoint32_(hDC, text$, Len(text$), sz.SIZE) ReleaseDC_(WindowID, hDC) ProcedureReturn sz\cy EndProcedure Now, don't tell me there was also a TextHeight() command in PB

It would be better if we wouldn't have to do StartDrawing() and StopDrawing() to know the width in pixels of a text. It would be faster. Time is monay  .
