Member Function Documentation

◆ CalcPreferredSize()

Size open3d::visualization::gui::Button::CalcPreferredSize ( const LayoutContext context,
const Constraints constraints 
) const

◆ Draw()

Widget::DrawResult open3d::visualization::gui::Button::Draw ( const DrawContext context)

Draws the widget. If this is a Dear ImGUI widget, this is where the actual event processing happens. Return NONE if no action needs to be taken, REDRAW if the widget needs to be redrawn (e.g. its value changed), and RELAYOUT if the widget wishes to change size.

Reimplemented from open3d::visualization::gui::Widget.

◆ GetHorizontalPaddingEm()

float open3d::visualization::gui::Button::GetHorizontalPaddingEm ( ) const

Returns the padding, in units of ems.

◆ GetIsOn()

bool open3d::visualization::gui::Button::GetIsOn ( ) const

◆ GetIsToggleable()

bool open3d::visualization::gui::Button::GetIsToggleable ( ) const

◆ GetText()

const char * open3d::visualization::gui::Button::GetText ( ) const

Returns the text of the button. If the button is an image, will return "".

◆ GetVerticalPaddingEm()

float open3d::visualization::gui::Button::GetVerticalPaddingEm ( ) const

◆ SetOn()

void open3d::visualization::gui::Button::SetOn ( bool  is_on)

◆ SetOnClicked()

void open3d::visualization::gui::Button::SetOnClicked ( std::function< void()>  on_clicked)

◆ SetPaddingEm()

void open3d::visualization::gui::Button::SetPaddingEm ( float  horiz_ems,
float  vert_ems 

Sets the padding, in units of ems. Note that for text buttons, a padding of (0, 0) will not actually give a padding of 0, there will be a small padding because having zero padding looks horrible and because this way a vertical padding of zero is exactly the same size as a text row, which means the button is the same size as the the other text-based widgets, so it will look nice with them.

◆ SetText()

void open3d::visualization::gui::Button::SetText ( const char *  text)

Sets the text of the button. Do not call if this is an image button.

◆ SetToggleable()

void open3d::visualization::gui::Button::SetToggleable ( bool  toggles)
