Hi,

How can I set the font size to a system font size. For example, if I wanted to set the font to the same size as it appears when you set the size to 10 under the Options screen.

Thanks.

Font.getDefaultFont() will return you the System default Font, if you haven't set a Default FOnt for the Application.  You can get the Size from that.  Is that what you wanted?

[SunnyDee]

Not quite, unless from Font.getDefault() I can get the size (again, not in pixels).

I want to allow the user to select the font size for use within my program:

ie: 7,8,9,10... or System font size

And since the screen resolution is different for various devices, I can't just set the height using the setHeight(int pixels) method, since a size 10 on one device will require a different height than a size 10 on another device.

I'd like for my font heights (7,8,9, etc) to match up with the devices...

THanks!

[peter_strange]

Can you factor the font height using Display.getVerticalResolution() to work out the size?

[SunnyDee]

That's what I was thinking, though if I could somehow get the font size to match up with the default ones used by the system, that would be ideal.

FYI:

FOund it:

public Font derive(int style,
                   int height,
                   int units)

Set units to Ui.UNITS_pt, then specify the size with the height variable

Okay so i have just spent the past 2 hours googling and searching including this forum on a simple example on how to set the font size for a handheld application and ran across this forum posting several times. I am not clear on how to implement the Font on the handheld.

Could you clarify exactly how to use the Font.derive please.
I tried the following but eclipse is yelling at me.

Font f = new Font();
Font.derive(Font.PLAIN, 10, Ui.UNITS_pt);
super.getActiveScreen().setFont(f);

Current time is 3:55pm EST. I am online for chat at PowerMountain Chat just enter in any user name to connect or post response to this forum please.

The Font class does not have a constructor.  You can use the static Font.getDefaultFont method to obtain the default font.  You can then call the derive method on the Font object returned from this method.

Hey, just in case someone else is wondering, here is the solution:

// First, derive the default font and modify it to be PLAIN and 10 pt

Font myFont = Font.getDefault().derive(Font.PLAIN, 10);

// Then, set the font to what you derived above

graphics.setFont(myFont );

// Then draw the text

graphics.drawText("Hello World", xpos, ypos);
