Detailed Description

Drop Down.

The control can be pressed, but we will not inherent this behavior from IGUIButtonBehavior, because when you press this control, the list with elements will immediately appear, and not first after release (which is the whole gist of the IGUIButtonBehavior).

Member Function Documentation

◆ Draw()

void CDropDown::Draw ( CCanvas2D & canvas )

virtual

Draws the Button.

Reimplemented from CList.

◆ GetBufferedZ()

float CDropDown::GetBufferedZ ( ) const

virtual

Returns not the Z value, but the actual buffered Z value, i.e.

if it's defined relative, then it will check its parent's Z value and add the relativity.

Returns: Actual Z value on the screen.

Reimplemented from IGUIObject.

◆ GetListRect()

CRect CDropDown::GetListRect ( ) const

Reimplemented from CList.

◆ HandleMessage()

void CDropDown::HandleMessage ( SGUIMessage & Message )

virtual

See also: IGUIObject::HandleMessage()

Reimplemented from CList.

◆ IsMouseOver()

bool CDropDown::IsMouseOver ( ) const

virtual

This function checks if the mouse is hovering the rectangle that the base setting "size" makes.

Although it is virtual, so one could derive an object from CButton, which changes only this to checking the circle that "size" makes.

This function also returns true if there is a different GUI object shown on top of this one.

Reimplemented from IGUIObject.

◆ ManuallyHandleKeys()

InReaction CDropDown::ManuallyHandleKeys ( const SDL_Event_ * ev )

virtual

Handle events manually to catch keyboard inputting.

Reimplemented from CList.

◆ SetupListRect()

void CDropDown::SetupListRect ( )

protectedvirtual

◆ SetupText()

void CDropDown::SetupText ( )

protectedvirtual

Sets up text, should be called every time changes has been made that can change the visual.

Reimplemented from CList.

◆ UpdateCachedSize()

void CDropDown::UpdateCachedSize ( )

protectedvirtual

If the size changed, the texts have to be updated as the word wrapping depends on the size.

Reimplemented from CList.
