Detailed Description

This is a base class for derived VDKCustomList and VDKCustomTree Provides common functionalities for both child classes.

Programming tips

VDKCustom operations are dependent on selection mode that can be one of the following:

• GTK_SELECTION_SINGLE (default)
• GTK_SELECTION_BROWSE
• GTK_SELECTION_MULTIPLE
• GTK_SELECTION_EXTENDED

Signals

Signals are available for all modes except browse one, but the way you can use them is different for each mode. Basically in single mode you may use Selection property while in other modes you may use Selections() method. It's possible to connect with "click_column" signal using dynamics tables provided that use connects with <gtk> arg set to false.

SignalConnect(aCustom, "click_column",&SomeClass::Response,false);

Member Function Documentation

void VDKCustom::ActiveTitle	(	int	col,
		bool	flag = true
	)

Sets/unsets active titile

Parameters

col,ordinal	position of the active title
flag,either	true (set) or false (unset)

void VDKCustom::ActiveTitles

(

bool

flag = true

)

Same as above but acts on the entire tuple.

void VDKCustom::AutoResizeColumn	(	int	col,
		bool	flag
	)

Sets/unsets column auto-resize capability

Parameters

col,ordinal	position
flag,either	true (sets) or false (unsets)

virtual void VDKCustom::Clear ( )

inlinevirtual

Clear widget

Reimplemented in VDKCustomList, and VDKCustomTree.

int VDKCustom::ColumnClicked ( )

inline

Returns wich column was clicked

void VDKCustom::ColumnSize	(	int	col,
		int	size
	)

Set column fixed size

Parameters

col,ordinal	position
size,in	pixels

GtkWidget* VDKCustom::CustomWidget ( )

inline

Returns underlying custom widget.

Tip:

Use this to access to custom widget, using VDKObject::Widget() will access to the widget container not to custom widget itself.

void VDKCustom::EnableTitles

(

bool

flag = true

)

Set/unset titles sensitivity

Parameters

flag,if

false titles will be grayed as well.

void VDKCustom::Freeze ( )

inline

Freezes widget during time consuming updating operations

GtkSelectionMode VDKCustom::SelectionMode

(

)

Returns selection mode

void VDKCustom::SetBackground ( VDKRgb  color, GtkStateType  state = GTK_STATE_NORMAL  )

protectedvirtual

Sets object background

Parameters

color	a VDKRgb object
state	can be one of the gtk+ widget states

Reimplemented from VDKObject.

void VDKCustom::SetFont ( VDKFont *  f )

virtual

Sets object font

Reimplemented from VDKObject.

void VDKCustom::SetForeground ( VDKRgb  color, GtkStateType  state  )

virtual

Sets object foreground

Parameters

color	a VDKRgb object
state	can be one of the gtk+ widget states

Reimplemented from VDKObject.

int VDKCustom::Size ( )

inline

Returns how many rows/nodes are into custom widget

void VDKCustom::Thaw ( )

inline

Unfreeze

Member Data Documentation

VDKReadWriteValueProp<VDKCustom,bool> VDKCustom::AutoResize

Use this to set/get auto resize capablity for al columns

VDKReadWriteValueProp<VDKCustom,GtkShadowType> VDKCustom::BorderShadow

Use this to get/set border shadow

VDKReadWriteValueProp<VDKCustom,GtkPolicyType> VDKCustom::HPolicy

Use this to get/set hor. scrollbar policy

VDKReadWriteValueProp<VDKCustom,int> VDKCustom::RowHeight

Use this to get/set row height

Tip

By default row height is computed using default font.

VDKReadWriteValueProp<VDKCustom,VDKRgb> VDKCustom::SelectedForeground

Use this to set colors for selected lines if they should be different from defaults. All new added rows will have this colors. VDKReadWriteValueProp<VDKCustom,VDKColor*> SelectedBackground;

Use this to set colors for selected lines if they should be different from defaults. All new added rows will have this colors.

VDKReadOnlyValueProp<VDKCustom,int> VDKCustom::SelectedTitle

<read-only>, use this to know wich title was selected (if any)

VDKObjectArray VDKCustom::Titles

Since column titles are themselves objects you can use this to access them and set object properties like this:

custom->Titles[0]->Enabled = false; 
custom->Titles[0]->Normalbackground = VDKRgb("dodgerblue");

VDKReadWriteValueProp<VDKCustom,VDKRgb> VDKCustom::UnselectedBackground

its use is deprecated, mantained for compat, reverts to NormalBackground

VDKReadWriteValueProp<VDKCustom,VDKRgb> VDKCustom::UnselectedForeground

its use is deprecated, mantained for compat, reverts to Foreground

VDKReadWriteValueProp<VDKCustom,GtkPolicyType> VDKCustom::VPolicy

Use this to get/set vert. scrollbar policy
