Cannot center align text

Postby Blackroot » Tue Dec 27, 2016 16:32

Hello beautiful peoples,

I'm having some trouble center-aligning some text, specifically the property I'm under the impression controls alignment doesn't appear to exist when I alter the property. (The specific widget I'm working on is a TaharezLook titlebar)

I poked at the XML files to try and find the correct property name,

Code: Select all

XML definition:
                <HorzFormat type="RightAligned" />

and also
        <PropertyDefinition name="HorzFormatting" initialValue="CentreAligned" redrawOnWrite="true" type="HorizontalTextFormatting" />
       


However, when I go to set either one of these definitions

Code: Select all

//   CEGUI::Titlebar* titlebar = static_cast<CEGUI::Titlebar*>(m_gui.createWidget("TaharezLook/Titlebar", glm::vec4(0.5f, 0.00f, .5f, .060f), glm::vec4(0), "Main Menu Titlebar"));
   titlebar->setProperty("HorzFormatting", "CentreAligned");
   //OR
   titlebar->setProperty("HorzFormat", "CentreAligned");


I'm being told "There is no property named 'X' in the set. I can't for the life of me figure out what I'm doing wrong, it seems like the property name I'm using must exist if the XML file is using it. I'd greatly appreciate clarification on this one! Cheers!

Did you debug and look into the property container of the window? What is in it?

The only property that struck me was HorizontalAlignment, but that set the window's horizontal alignment. Bollocks!

Any ideas?

From looking at "TaharezLook.looknfeel" it seems there's no control over the text alignment. However, if u want to add such control, I think it should b easy: look e.g. at how "TaharezLook/Label" is defined in that file, specifically search for ""HorzFormatting".

Ahh! I had thought this was a native property for widgets, guess I was wrong! Simple fix, thanks for the help!

For any curious peoples,

Code: Select all

//Widget header
   <PropertyDefinition name="HorzFormatting" initialValue="CentreAligned" redrawOnWrite="true" type="HorizontalTextFormatting" />
      
        <ImagerySection name="caption">
            <TextComponent>
                <Area>
                    <Dim type="LeftEdge" ><ImageDim name="TaharezLook/NewTitlebarLeft" dimension="Width" /></Dim>
                    <Dim type="Width" ><UnifiedDim scale="1" offset="-75" type="Width" /></Dim>
                </Area>
                <ColourProperty name="CaptionColour" />
                <VertFormat type="CentreAligned" />
      <HorzFormatProperty name="HorzFormatting" />
            </TextComponent>
        </ImagerySection>

We got a property list for the included skins for each widget, available here: http://static.cegui.org.uk under "Property lists (for LookNFeel skins)"

We should probably also document the native properties better. We had this one in 0.7.X which was quite perfect: http://static.cegui.org.uk/docs/0.7.9/n ... CEGUI.html

The docu has been changed since, as this part has been refactored, and something equally good (or better) has not been put in place yet. Maybe someone skilled enough got an idea how to do it?

The perfect situation would imo be to have an overview for core classes and the falagard classes (in two separate section) , the rest could be similar to the above link.

We should probably autogenerate something like that on each doxy run.

@Ident: I think we should make in the official cegui a change similar to what @Blackroot has done (and in other look`n`feel files, if they miss it). What do u think?

@Ident: I'm gonna keep the default horizontal text alignment as "left" in branches "v0-8" and "v0" in order to maintain behaviour, but change it to "center" in branch "default". Comments?

@Ident: Actually, I even consider removing the property in branch "default" and make it always centre aligned. Of course, it's still possible to add the property in the look`n`feel file. What do u think?

Can you explain the reasoning behind it? Isn't it good to have the option?

@Blackroot: Glad to help, and thanx for helping us catch that issue and improve it in our next release.

If you're interested, feel free to share with us about the project u work on (in the dedicated forum).

@Ident: Sure it's good.. however by that reasoning I guess we could add many other properties in the look`n`feel files. I think properties which r rarely useful shouldn't b added to our distributed look`n`feel files. Now, I ask myself, is left or right alignment useful here? I dunno.. I think titlebars almost always use centre-aligned text, and I think it makes sense to do that. But I could b wrong.

Btw e.g. in "Vanilla.looknfeel" it's always centre aligned (without a property).

Thanks for the reminder.

What about just adding a new property for this to the FalagardTitlebar, then we don't need to do anything in the look n feel files?

Edit: Default alignment? No clue. I would go by what is the most commonly used one for our current widgets.

But what I wanna do is the opposite: I think users will rarely want a titlebar that's not center aligned (though I'm not sure about it and would b glad to hear other views). Therefore I'd like to remove it from all look`n`feel files where a titlebar contains a horizontal text alignment property (it's not all of them), and users still wishing to use left or right alignment can add it to the look`n`feel file (which is just a matter of adding 2 or 3 lines).
