Change fonts on all controls

General

Hey guys… I have this question… How do I change the font all over the app ?
I mean… I suppose I don’t have to go in EVERY control and change the font… or do I ?
TIA

Do you need to do this 1) once or 2) do you want to make your app have a preferences for different fonts?

  1. Yes, do it manually.
  2. Use the Observer pattern. There should be an example if the Xojo examples folder.

I thought I could do this from the IDE… Just want to change the look of the UI…

I’ll check out the example you mentioned…

You can do this. It’s just a bit of work. You need to make sure that there is enough space, though. For instance, I my own app I have 5 areas where I allow the user to change the font and the font size.

The observer pattern is as follows: you have a subject, for the font that would be where you show the user the font list. The controls then implement an interface called observer. Whenever the font is changed the observer gets notified and is responsible to change the font.

I think I got the idea regarding the observer pattern method… Not 100% sure I would know how to code it…

But still, I don’t want the user to select the font… I just want to change the appearance of the controls in my app. After a lot of time I realized that the font I chose wasn’t the font that better fits my app… But I will definitely NOT go one by one, every single control…

Thanks

I might misunderstand, but if you want to change all fonts while developing in the IDE, not when running, just search project and replace those you want. Ie: seach for Courier New and replace it with Dingbats for fun.

That did the trick, Peter… I just have to be a bit careful, as the current font is ‘system’ so that keyword appears quite a few times…

thanks!

Roman, didn’t I ask you what you want to do???

I thought I had answered you… Sorry If I wasn’t clear enough.

Another (more manual) way is to select all the controls with a font and then the properties pane font section will modify them all.

You have to select only those controls with a font as the properties pane only show those properties common to all selected. And you’ll have to go through each Window and ContainerControl individually. More steps than search/replace but just something to know.

I use this method in all windows …
kk_font is a constant in main module apps

dim c as control
for i as integer = 0 to self.ControlCount -1
c = self.Control(i)
// this is my custom control
if c IsA TextFieldKoala then
TextFieldKoala©.TextFont = Minicontab.kk_font
end if

if c IsA Label then
  Label(c).TextFont = Minicontab.kk_font
end if

if c isA GroupBox then
  GroupBox(c).TextFont = Minicontab.kk_font
end if

if c isA CheckBox then
  CheckBox(c).TextFont = Minicontab.kk_font
end if

if c isA ComboBox then
  ComboBox(c).TextFont = Minicontab.kk_font
end if

if c isA RadioButton then
  RadioButton(c).TextFont = Minicontab.kk_font
end if

if c isA Listbox then
  Listbox(c).TextFont = Minicontab.kk_font
end if

if c isA PopupMenu then
  PopupMenu(c).TextFont = Minicontab.kk_font
end if

if c isA TextArea then
  TextArea(c).TextFont = Minicontab.kk_font
end if

if c isA TabPanel then
  TabPanel(c).TextFont = Minicontab.kk_font
end if

if c isA PushButton then
  PushButton(c).TextFont = Minicontab.kk_font
end if

next
