# wx.PickerBase¶

Base abstract class for all pickers which support an auxiliary text control.

This class handles all positioning and sizing of the text control like a an horizontal wx.BoxSizer would do, with the text control on the left of the picker button.

The proportion (see wx.Sizer documentation for more info about proportion values) of the picker control defaults to 1 when there isn’t a text control associated (see PB_USE_TEXTCTRL style) and to 0 otherwise.

## Window Styles¶

This class supports the following styles:

• wx.PB_USE_TEXTCTRL: Creates a text control to the left of the picker which is completely managed by this wx.PickerBase class.

## Methods Summary¶

 __init__ CreateBase GetInternalMargin Returns the margin (in pixel) between the picker and the text control. GetPickerCtrl Returns the native implementation of the real picker control. GetPickerCtrlProportion Returns the proportion value of the picker. GetPickerStyle GetTextCtrl Returns a pointer to the text control handled by this window or None if the PB_USE_TEXTCTRL style was not specified when this control was created. GetTextCtrlProportion Returns the proportion value of the text control. GetTextCtrlStyle HasTextCtrl Returns True if this window has a valid text control (i.e. if the PB_USE_TEXTCTRL style was given when creating this control). IsPickerCtrlGrowable Returns True if the picker control is growable. IsTextCtrlGrowable Returns True if the text control is growable. PostCreation SetInternalMargin Sets the margin (in pixel) between the picker and the text control. SetPickerCtrl SetPickerCtrlGrowable Sets the picker control as growable when grow is True. SetPickerCtrlProportion Sets the proportion value of the picker. SetTextCtrl SetTextCtrlGrowable Sets the text control as growable when grow is True. SetTextCtrlProportion Sets the proportion value of the text control. UpdatePickerFromTextCtrl UpdateTextCtrlFromPicker

## Class API¶

class wx.PickerBase(Control)

Possible constructors:

PickerBase()


Base abstract class for all pickers which support an auxiliary text control.

### Methods¶

__init__(self)

CreateBase(self, parent, id=ID_ANY, text="", pos=DefaultPosition, size=DefaultSize, style=0, validator=DefaultValidator, name=ButtonNameStr)
Parameters
Return type

bool

GetInternalMargin(self)

Returns the margin (in pixel) between the picker and the text control.

This function can be used only when HasTextCtrl returns True.

Return type

int

GetPickerCtrl(self)

Returns the native implementation of the real picker control.

Return type

wx.Control

Note

The returned control in the generic implementation of wx.FilePickerCtrl, wx.DirPickerCtrl, wx.FontPickerCtrl and wx.ColourPickerCtrl is a specialized wx.Button class so that you can change its label doing, e.g.:

if wx.Platform == '__WXMSW__':
# wxMSW is one of the platforms where the generic implementation
# of wx.FilePickerCtrl is used...

pButt = myFilePickerCtrl.GetPickerCtrl()

if pButt is not None:
pButt.SetLabel('Custom browse string')


GetPickerCtrlProportion(self)

Returns the proportion value of the picker.

Return type

int

GetPickerStyle(self, style)
Parameters

style (long) –

Return type

long

GetTextCtrl(self)

Returns a pointer to the text control handled by this window or None if the PB_USE_TEXTCTRL style was not specified when this control was created.

Return type

wx.TextCtrl

Note

The contents of the text control could be an invalid representation of the entity which can be chosen through the picker (e.g. when the user enters an invalid colour syntax because of a typo). Thus you should never parse the content of the textctrl to get the user’s input; rather use the derived-class getter (e.g. wx.ColourPickerCtrl.GetColour , wx.FilePickerCtrl.GetPath , etc).

GetTextCtrlProportion(self)

Returns the proportion value of the text control.

This function can be used only when HasTextCtrl returns True.

Return type

int

GetTextCtrlStyle(self, style)
Parameters

style (long) –

Return type

long

HasTextCtrl(self)

Returns True if this window has a valid text control (i.e. if the PB_USE_TEXTCTRL style was given when creating this control).

Return type

bool

IsPickerCtrlGrowable(self)

Returns True if the picker control is growable.

Return type

bool

IsTextCtrlGrowable(self)

Returns True if the text control is growable.

This function can be used only when HasTextCtrl returns True.

Return type

bool

PostCreation(self)

SetInternalMargin(self, margin)

Sets the margin (in pixel) between the picker and the text control.

This function can be used only when HasTextCtrl returns True.

Parameters

margin (int) –

SetPickerCtrl(self, picker)
Parameters

picker (wx.Control) –

SetPickerCtrlGrowable(self, grow=True)

Sets the picker control as growable when grow is True.

Parameters

grow (bool) –

SetPickerCtrlProportion(self, prop)

Sets the proportion value of the picker.

Parameters

prop (int) –

SetTextCtrl(self, text)
Parameters

text (wx.TextCtrl) –

SetTextCtrlGrowable(self, grow=True)

Sets the text control as growable when grow is True.

This function can be used only when HasTextCtrl returns True.

Parameters

grow (bool) –

SetTextCtrlProportion(self, prop)

Sets the proportion value of the text control.

This function can be used only when HasTextCtrl returns True.

Parameters

prop (int) –

UpdatePickerFromTextCtrl(self)
