Detailed Description

Text field where you can input and edit the text.

It doesn't use IGUITextOwner, because we don't need any other features than word-wrapping, and we need to be able to rapidly change the string.

Conventions for Left/Right when text is selected:

References:

Visual Studio Visual Studio has the 'newer' approach, used by newer versions of things, and in newer applications. A left press will always place the pointer on the left edge of the selection, and then of course remove the selection. Right will do the exact same thing. If you have the pointer on the right edge and press right, it will in other words just remove the selection.

Windows (eg. Notepad) A left press always takes the pointer a step to the left and removes the selection as if it were never there in the first place. Right of course does the same thing but to the right.

I chose the Visual Studio convention. Used also in Word, gtk 2.0, MSN Messenger.

Conventions for Up/Down when text is selected:

References:

Visual Studio Visual Studio has a very strange approach, down takes you below the selection to the next row, and up to the one prior to the whole selection. The weird part is that it is always aligned as the 'pointer'. I decided this is to much work for something that is a bit arbitrary

Windows (eg. Notepad) Just like with left/right, the selection is destroyed and it moves just as if there never were a selection.

I chose the Notepad convention even though I use the VS convention with left/right.

◆ ManuallyMutableHandleKeyDownEvent()

void CInput::ManuallyMutableHandleKeyDownEvent ( const SDL_Keycode keyCode )

protectedvirtual

Handle events manually to catch keys which change the text.

◆ SelectingText()

bool CInput::SelectingText ( ) const

protected

Is text selected? It can be denote two ways, m_iBufferPos_Tail being -1 or the same as m_iBufferPos.

This makes for clearer code.

◆ SetupGeneratedPlaceholderText()

void CInput::SetupGeneratedPlaceholderText ( )

protected

◆ UpdateAutoScroll()

void CInput::UpdateAutoScroll ( )

protected

Called every time the auto-scrolling should be checked.

◆ UpdateBufferPositionSetting()

void CInput::UpdateBufferPositionSetting ( )

protected

Updates the buffer (cursor) position exposed to JS.

◆ UpdateCachedSize()

void CInput::UpdateCachedSize ( )

protectedvirtual

See also: IGUIObject::UpdateCachedSize()

Reimplemented from IGUIObject.

◆ UpdateText()

void CInput::UpdateText	(	int	from = `0`,
		int	to_before = `-1`,
		int	to_after = `-1`
	)

protected

Calculate m_CharacterPosition the main task for this function is to perfom word-wrapping You input from which character it has been changed, because if we add a character to the very last end, we don't want process everything all over again! Also notice you can specify a 'to' also, it will only be used though if a '
' appears, because then the word-wrapping won't change after that.
