wxbu_left	left-justifies the label. windows and gtk+ only.
wxbu_top	aligns the label to the top of the button. windows and gtk+ only.
wxbu_right	right-justifies the bitmap label. windows and gtk+ only.
wxbu_bottom	aligns the label to the bottom of the button. windows and gtk+ only.
wxbu_exactfit	creates the button as small as possible instead of making it of the standard size (which is the default behaviour ).
wxno_border	creates a flat button. windows and gtk+ only.

wxbutton::wxbutton

wxbutton()

default constructor.

wxbutton(wxwindow* parent, wxwindowid id, const wxstring& label = wxemptystring, const wxpoint& pos = wxdefaultposition, const wxsize& size = wxdefaultsize, long style = 0, const wxvalidator& validator = wxdefaultvalidator, const wxstring& name = "button")

constructor, creating and showing a button.

the preferred way to create standard buttons is to use default value of label. if no label is supplied and id is one of standard ids from this list, standard label will be used. in addition to that, the button will be decorated with stock icons under gtk+ 2.

parameters

parent

parent window. must not be null.

wxid_any

label

text to be displayed on the button.

pos

button position.

size

button size. if the default size is specified then the button is sized appropriately for the text.

style

wxbutton

validator

window validator.

name

window name.

wxbutton::create, wxvalidator

wxbutton::~wxbutton

~wxbutton()

destructor, destroying the button.

wxbutton::create

bool create(wxwindow* parent, wxwindowid id, const wxstring& label = wxemptystring, const wxpoint& pos = wxdefaultposition, const wxsize& size = wxdefaultsize, long style = 0, const wxvalidator& validator, const wxstring& name = "button")

button creation function for two-step creation. for more details, see wxbutton::wxbutton.

wxbutton::getlabel

wxstring getlabel() const

returns the string label for the button.

return value

the button's label.

wxbutton::setlabel

wxbutton::getdefaultsize

wxsize getdefaultsize()

returns the default size for the buttons. it is advised to make all the dialog buttons of the same size and this function allows to retrieve the (platform and current font dependent size) which should be the best suited for this.

wxbutton::setdefault

void setdefault()

this sets the button to be the default item for the panel or dialog box.

remarks

under windows, only dialog box buttons respond to this function. as normal under windows and motif, pressing return causes the default button to be depressed when the return key is pressed. see also wxwindow::setfocus which sets the keyboard focus for windows and text panel items, and wxtoplevelwindow::setdefaultitem.

note that under motif, calling this function immediately after creation of a button and before the creation of other buttons will cause misalignment of the row of buttons, since default buttons are larger. to get around this, call setdefault after you have created a row of buttons: wxwidgets will then set the size of all buttons currently on the panel to the same size.

wxbutton::setlabel

void setlabel(const wxstring& label)

sets the string label for the button.

parameters

label

the label to set.
