wx.StdDialogButtonSizer

This class creates button layouts which conform to the standard button spacing and ordering defined by the platform or toolkit’s user interface guidelines (if such things exist).

By using this class, you can ensure that all your standard dialogs look correct on all major platforms. Currently it conforms to the Windows, GTK+ and macOS human interface guidelines.

When there aren’t interface guidelines defined for a particular platform or toolkit, wx.StdDialogButtonSizer reverts to the Windows implementation.

To use this class, first add buttons to the sizer by calling wx.StdDialogButtonSizer.AddButton (or wx.StdDialogButtonSizer.SetAffirmativeButton , wx.StdDialogButtonSizer.SetNegativeButton or wx.StdDialogButtonSizer.SetCancelButton ) and then call Realize in order to create the actual button layout used. Other than these special operations, this sizer works like any other sizer.

If you add a button with wx.ID_SAVE, on macOS the button will be renamed to “Save” and the wx.ID_NO button will be renamed to “Don’t Save” in accordance with the macOS Human Interface Guidelines.

Class API

class wx.StdDialogButtonSizer(BoxSizer)

Possible constructors:

StdDialogButtonSizer()

This class creates button layouts which conform to the standard button spacing and ordering defined by the platform or toolkit’s user interface guidelines (if such things exist).

Methods

__init__(self)

Constructor for a wx.StdDialogButtonSizer.

---

AddButton(self, button)

Adds a button to the wx.StdDialogButtonSizer.

The button must have one of the following identifiers:

• wx.ID_OK

• wx.ID_YES

• wx.ID_SAVE

• wx.ID_APPLY

• wx.ID_CLOSE

• wx.ID_NO

• wx.ID_CANCEL

• wx.ID_HELP

• wx.ID_CONTEXT_HELP

Parameters:

button (wx.Button) –

---

CalcMin(self)

Implements the calculation of a box sizer’s minimal.

It is used internally only and must not be called by the user. Documented for information.

Return type:

wx.Size

---

Realize(self)

Rearranges the buttons and applies proper spacing between buttons to make them match the platform or toolkit’s interface guidelines.

---

RepositionChildren(self, minSize)

Method which must be overridden in the derived sizer classes.

The implementation should reposition the children using the current total size available to the sizer ( m_size ) and the size computed by the last call to CalcMin .

Parameters:

minSize (wx.Size) –

New in version 4.1/wxWidgets-3.1.3: , before this version RecalcSizes() method not taking any arguments had to be overridden in the derived classes instead.

---

SetAffirmativeButton(self, button)

Sets the affirmative button for the sizer.

This allows you to use identifiers other than the standard identifiers outlined above.

Parameters:

button (wx.Button) –

---

SetCancelButton(self, button)

Sets the cancel button for the sizer.

This allows you to use identifiers other than the standard identifiers outlined above.

Parameters:

button (wx.Button) –

---

SetNegativeButton(self, button)

Sets the negative button for the sizer.

This allows you to use identifiers other than the standard identifiers outlined above.

Parameters:

button (wx.Button) –
