Inheritance diagram for wxInfoBar:

Detailed Description

An info bar is a transient window shown at top or bottom of its parent window to display non-critical information to the user.

This class provides another way to show messages to the user, intermediate between message boxes and status bar messages. The message boxes are modal and thus interrupt the users work flow and should be used sparingly for this reason. However status bar messages are often too easy not to notice at all. An info bar provides a way to present the messages which has a much higher chance to be noticed by the user but without being annoying.

Info bar may show an icon (on the left), text message and, optionally, buttons allowing the user to react to the information presented. It always has a close button at the right allowing the user to dismiss it so it isn't necessary to provide a button just to close it.

wxInfoBar calls its parent wxWindow::Layout() method and assumes that it will change the parent layout appropriately depending on whether the info bar itself is shown or hidden. Usually this is achieved by simply using a sizer for the parent window layout and adding wxInfoBar to this sizer as one of the items. Considering the usual placement of the info bars, normally this sizer should be a vertical wxBoxSizer and the bar its first or last element so the simplest possible example of using this class would be:

class MyFrame : public wxFrame
{
    ...

    wxInfoBar *m_infoBar;
};

MyFrame::MyFrame()
{
    ...
    m_infoBar = new wxInfoBar(this);

    wxSizer *sizer = new wxBoxSizer(wxVERTICAL);
    sizer->Add(m_infoBar, wxSizerFlags().Expand());
    ... add other frame controls to the sizer ...
    SetSizer(sizer);
}

void MyFrame::SomeMethod()
{
    m_infoBar->ShowMessage("Something happened", wxICON_INFORMATION);
}

See the dialogs sample for more sophisticated examples.

Currently this class is implemented generically (i.e. in the same platform-independent way for all ports) and also natively in wxGTK but the native implementation requires a recent – as of this writing – GTK+ 2.18 version.

Constructor & Destructor Documentation

wxInfoBar::wxInfoBar

(

)

Default constructor.

Use Create() for the objects created using this constructor.

wxInfoBar::wxInfoBar	(	wxWindow *	parent,
		wxWindowID	winid = wxID_ANY
	)

Constructor creating the info bar window.

Member Function Documentation

void wxInfoBar::AddButton	(	wxWindowID	btnid,
		const wxString &	label = wxString()
	)

Add a button to be shown in the info bar.

The button added by this method will be shown to the right of the text (in LTR layout), with each successive button being added to the right of the previous one. If any buttons are added to the info bar using this method, the default "Close" button is not shown as it is assumed that the extra buttons already allow the user to close it.

Clicking the button will generate a normal EVT_COMMAND_BUTTON_CLICKED event which can be handled as usual. The default handler in wxInfoBar itself closes the window whenever a button in it is clicked so if you wish the info bar to be hidden when the button is clicked, simply call event.Skip() in the button handler to let the base class handler do it (calling Dismiss() explicitly works too, of course). On the other hand, if you don't skip the event, the info bar will remain opened so make sure to do it for at least some buttons to allow the user to close it.

Notice that the generic wxInfoBar implementation handles the button events itself and so they are not propagated to the info bar parent and you need to either inherit from wxInfoBar and handle them in your derived class or use wxEvtHandler::Connect(), as is done in the dialogs sample, to handle the button events in the parent frame.

Parameters

btnid	Id of the button. It will be used in the button message clicking this button will generate.
label	The label of the button. It may only be empty if btnid is one of the stock ids in which case the corresponding stock label (see wxGetStockLabel()) will be used.

bool wxInfoBar::Create	(	wxWindow *	parent,
		wxWindowID	winid = wxID_ANY
	)

Create the info bar window.

Notice that unlike most of the other wxWindow-derived classes, wxInfoBar is created hidden and is only shown when ShowMessage() is called. This is more convenient as usually the info bar is created to be shown at some later time and not immediately and so creating it hidden avoids the need to call Hide() explicitly from the code using it.

This should be only called if the object was created using its default constructor.

Parameters

parent	A valid parent window pointer.
winid	The id of the info bar window, usually unused as currently no events are generated by this class.

virtual void wxInfoBar::Dismiss ( )

virtual

Hide the info bar window.

This method hides the window and lays out the parent window to account for its disappearance (unlike a simple Hide()).

virtual size_t wxInfoBar::GetButtonCount ( ) const

virtual

Returns the number of currently shown buttons.

This is simply the number of calls to AddButton() minus the number of calls to RemoveButton() so far.

Returns

The number of currently shown buttons, possibly 0.

Since

3.1.0

virtual wxWindowID wxInfoBar::GetButtonId ( size_t  idx ) const

virtual

Returns the ID of the button at the given position.

The positions of the buttons are counted in order of their addition.

Parameters

idx	The position of the button in 0 to GetButtonCount() range.

Returns

The ID of the button at the given position or wxID_NONE if it is out of range (this also results in an assertion failure).

Since

3.1.0

int wxInfoBar::GetEffectDuration

(

)

const

Return the effect animation duration currently used.

wxShowEffect wxInfoBar::GetHideEffect

(

)

const

Return the effect currently used for hiding the bar.

wxShowEffect wxInfoBar::GetShowEffect

(

)

const

Return the effect currently used for showing the bar.

virtual bool wxInfoBar::HasButtonId ( wxWindowID  btnid ) const

virtual

Returns whether a button with the given ID is currently shown.

Parameters

btnid

ID of the button to check for.

Returns

true if the button with this ID is currently shown.

Since

3.1.0

void wxInfoBar::RemoveButton

(

wxWindowID

btnid

)

Remove a button previously added by AddButton().

Parameters

btnid

Id of the button to remove. If more than one button with the same id is used in the info bar (which is in any case not recommended), the last, i.e. most recently added, button with this id is removed.

void wxInfoBar::SetEffectDuration

(

int

duration

)

Set the duration of the animation used when showing or hiding the bar.

By default, 500ms duration is used.

Parameters

duration

Duration of the animation, in milliseconds.

virtual bool wxInfoBar::SetFont ( const wxFont &  font )

virtual

Overridden base class methods changes the font of the text message.

wxInfoBar overrides this method to use the font passed to it for its text message part. By default a larger and bold version of the standard font is used.

This method is generic-only.

Reimplemented from wxWindow.

void wxInfoBar::SetShowHideEffects	(	wxShowEffect	showEffect,
		wxShowEffect	hideEffect
	)

Set the effects to use when showing and hiding the bar.

Either or both of the parameters can be set to wxSHOW_EFFECT_NONE to disable using effects entirely.

By default, the info bar uses wxSHOW_EFFECT_SLIDE_TO_BOTTOM effect for showing itself and wxSHOW_EFFECT_SLIDE_TO_TOP for hiding if it is the first element of the containing sizer and reverse effects if it's the last one. If it is neither the first nor the last element, no effect is used to avoid the use of an inappropriate one and this function must be called if an effect is desired.

Parameters

showEffect	The effect to use when showing the bar.
hideEffect	The effect to use when hiding the bar.

void wxInfoBar::ShowMessage	(	const wxString &	msg,
		int	flags = wxICON_NONE
	)

Show a message in the bar.

If the bar is currently hidden, it will be shown. Otherwise its message will be updated in place.

Parameters

msg

The text of the message.

flags

One of wxICON_NONE, wxICON_INFORMATION (default), wxICON_QUESTION, wxICON_WARNING or wxICON_ERROR values. These flags have the same meaning as in wxMessageDialog for the generic version, i.e. show (or not, in case of wxICON_NONE) the corresponding icon in the bar but can be interpreted by the native versions. For example, the GTK+ native implementation doesn't show icons at all but uses this parameter to select the appropriate background colour for the notification.
