## wxPickerBase

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 wxBoxSizer would do, with the text control on the left of the picker button. The proportion (see wxSizer documentation for more info about proportion values) of the picker control defaults to 1 when there isn't a text control associated (see `wxPB_USE_TEXTCTRL` style) and to 0 otherwise.

### wxPickerBase::SetInternalMargin

void SetInternalMargin(int margin)

Sets the margin (in pixel) between the picker and the text control. This function can be used only when HasTextCtrl returns `true`.

### wxPickerBase::GetInternalMargin

int GetInternalMargin() const

Returns the margin (in pixel) between the picker and the text control. This function can be used only when HasTextCtrl returns `true`.

### wxPickerBase::SetTextCtrlProportion

void SetTextCtrlProportion(int prop)

Sets the proportion value of the text control. Look at the overview of wxPickerBase for more details about this. This function can be used only when HasTextCtrl returns `true`.

### wxPickerBase::SetPickerCtrlProportion

void SetPickerCtrlProportion(int prop)

Sets the proportion value of the picker. Look at the overview of wxPickerBase for more details about this.

### wxPickerBase::GetTextCtrlProportion

int GetTextCtrlProportion() const

Returns the proportion value of the text control. This function can be used only when HasTextCtrl returns `true`.

### wxPickerBase::GetPickerCtrlProportion

int GetPickerCtrlProportion() const

Returns the proportion value of the picker.

### wxPickerBase::HasTextCtrl

bool HasTextCtrl() const

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

### wxPickerBase::GetTextCtrl

wxTextCtrl * GetTextCtrl()

Returns a pointer to the text control handled by this window or `NULL` if the wxPB_USE_TEXTCTRL style was not specified when this control was created. Very important: the contents of the text control could be containing an invalid representation of the entity which can be chosen through the picker (e.g. the user entered 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. wxColourPickerCtrl::GetColour, wxFilePickerCtrl::GetPath, etc).

### wxPickerBase::IsTextCtrlGrowable

bool IsTextCtrlGrowable() const

Returns `true` if the text control is growable. This function can be used only when HasTextCtrl returns `true`.

### wxPickerBase::SetPickerCtrlGrowable

void SetPickerCtrlGrowable(bool grow = true)

Sets the picker control as growable when `grow` is `true`.

### wxPickerBase::SetTextCtrlGrowable

void SetTextCtrlGrowable(bool grow = true)

Sets the text control as growable when `grow` is `true`. This function can be used only when HasTextCtrl returns `true`.

### wxPickerBase::IsPickerCtrlGrowable

bool IsPickerCtrlGrowable() const

Returns `true` if the picker control is growable.
