Detailed Description

Base class for all UI controls in a dialog.

This class provides basic functionality for all its child classes (such as position, visibility and size), but a control can't be created from the FCControl class alone. Instead, use the child classes.

Todo:
Fix issue where NSButton controls on macOS creep up the window when SetHeight is called during the lifetime of the window.

Requires PDK_FRAMEWORK_DIALOGS to be defined.

Member Enumeration Documentation

◆ CONTROL_ACTIONS

Predefined actions for controls.

These constants is only used for push buttons.

Constructor & Destructor Documentation

◆ FCControl() [1/2]

FCControl::FCControl ( twobyte  id,
const __FCControlTypedPtr &  subclassPtr 
)
inline

The constructor.

Parameters
idA unique value that identifies this control. You can use it in callback handlers to identify the control that is receiving the callback.
subclassPtrSubclasses should pass this for subclassPtr. It allows FCControl to access the correct subtype for the control.

Example

FCCtrlEdit(twobyte id) : FCControl(id, this) // constructor for FCCtrlEdit
{}
Base class for all UI controls in a dialog.
Definition: ff_dialogs.h:1476
Class that handles edit controls.
Definition: ff_dialogs.h:2650

◆ FCControl() [2/2]

FCControl::FCControl ( twobyte  id)
inline

The constructor for external C++ subclasses.

Parameters
idA unique value that identifies this control. You can use it in callback handlers to identify the control that is receiving the callback.

Member Function Documentation

◆ AssureNoHorizontalOverlap()

void FCControl::AssureNoHorizontalOverlap ( const FCControl control,
int  padding 
)
inline

Shift the control right as needed to the extent necessary so that its GetLeft position will accommodate the width of the specified control plus the specified padding. You can call this function with more than one reference control.

AssureNoHorizontalOverlap never reduces the GetLeft position. It either leaves it alone or increases it as needed.

To have an effect, this function must be called before the window is running, It does not work with buttons created using FCCustomWindow::CreateOkButton or FCCustomWindow::CreateCancelButton.

Lua-supported (0.71).

Parameters
controlthe reference control from which to assure no horizontal overlap
paddingadditional padding to assure exists between the reference control and this control

◆ AssureWidthForText()

bool FCControl::AssureWidthForText ( )
virtual

Lengthens the width of the control to the extent necessary to display all the text in the control.

The window must be running. AssureWidthForText never makes a control narrower than it already is. Use DoAutoResizeWidth to request this feature before the window is running.

AssureWidthForText works consistently across macOS and Windows for the following types of controls:

For other control types, the result (if any) is not guaranteed to be consistent or even effective.

Lua-supported (0.71).

Returns
true if success; false if the Window is not running or other error.

Reimplemented in FCCtrlPopup, and FCCtrlComboBox.

◆ ClassName()

const char * FCControl::ClassName ( ) const
inlineoverridevirtual

Returns the name of the class, for diagnostic purposes. This method MUST be overwritten in each child class.

Lua-supported.

Implements __FCBase.

Reimplemented in FCCtrlUpDown, FCCtrlLine, FCCtrlHorizontalLine, FCCtrlVerticalLine, FCCtrlStatic, FCCtrlEdit, FCCtrlPopup, FCCtrlComboBox, FCCtrlTextEditor, FCCtrlDataList, FCCtrlListBox, FCCtrlTree, FCCtrlSwitcher, FCCtrlRadioButton, FCCtrlCheckbox, FCCtrlButton, FCCtrlSlider, and FCCtrlImage.

◆ CreateFontInfo()

FCFontInfo * FCControl::CreateFontInfo ( ) const
virtual

Creates font information from the current text font of the control.

See SetFont for a discussion of the information that is copied and differences between OS platforms. You can call this function before the window is running to get a copy a font you have already set with SetFont. Otherwise, CreateFontInfo returns NULL until the window is running. After the window is running, CreateFontInfo returns a copy of the control's font, irrespective of whether you have ever called SetFont previously.

C++ clients must dispose of the pointer after use. Lua scripts do not need to worry about this.

Lua-supported (0.64).

Returns
Control's text font or NULL if error or if the window is not running and SetFont has never been called.

◆ DoAutoResizeWidth()

void FCControl::DoAutoResizeWidth ( std::optional< double >  minimumwidth = std::nullopt)
inline

Sets the autoresize width option for the control. When this value is set, the control calls AssureWidthForText automatically when the window initializes and every time SetText is called while the window is running.

You can optionally set the minimum width for the control. If you omit it it, the current width of the control (whether explicitly set or the default) becomes the minimum width. A subsequent call to SetWidth overrides any minimum width set here.

Call this function before the window is running. See AssureWidthForText for more information.

Lua-supported (0.71).

Parameters
minimumwidth(optional on both C++ and Lua) if present, set the minumum width to this value

◆ GetAction()

CONTROL_ACTIONS FCControl::GetAction ( ) const
inline

Returns the dialog acction assigned to the control.

Actions is only used for push buttons.

◆ GetAssignedID()

int FCControl::GetAssignedID ( ) const
inline

Gets the connected ID regardless of platform.

Use GetControlID to obtain the ID actually used in the native windowing system.

◆ GetControlID()

int FCControl::GetControlID ( ) const
inline

Returns the control ID for the control.

On Windows and Cocoa, this is the ID itself.

This implementation is for legacy reasons (Carbon). On current platforms, there is no difference between this method and GetAssignedID.

Lua-supported

Returns
If the control hasn't been added correctly to the dialog collection, -1 is returned.

◆ GetEnable()

bool FCControl::GetEnable ( ) const
virtual

Returns the enable/grayed state of the control (if user input should be allowed or not).

Technical: This version is virtual, so child classes can override with custom functionality. (If child classes overwrite, this implementation must be called if WindowExists() returns false.)

Lua-supported

◆ GetHeight()

float FCControl::GetHeight ( )

Returns the height of the control.

Lua-supported.

◆ GetLeft()

float FCControl::GetLeft ( )

Returns the left position of the control.

Lua-supported.

◆ GetPointsMeasurement()

bool FCControl::GetPointsMeasurement ( )
inline

Returns if the measurements and positioning is in points or in a system-native unit.

This is set automatically.

◆ GetText()

void FCControl::GetText ( FCString pString) const
virtual

Gets the text of the control.

Lua-supported.

◆ GetTop()

float FCControl::GetTop ( )

Returns the top position of the control.

Lua-supported.

◆ GetVisible()

bool FCControl::GetVisible ( )

Returns the visibility state of a control.

Lua-supported.

◆ GetWidth()

float FCControl::GetWidth ( )

Returns the width of the control.

Lua-supported.

◆ HorizontallyAlignLeftWith()

void FCControl::HorizontallyAlignLeftWith ( const FCControl pControl,
double  offset = 0 
)
inline

Specifies a control with which to horizontally align left. All controls set to align with this control align at the location of the one with the largest GetLeft value. This function replaces any previous alignment options.

To have an effect, this function must be called before the window is running, It does not work with buttons created using FCCustomWindow::CreateOkButton or FCCustomWindow::CreateCancelButton.

Lua-supported (0.71)

Parameters
pControlthe control to align with: if NULL, then alignment is disabled
offset(optional for C++ and Lua) an amount to offset from the alignment point; default is 0

◆ HorizontallyAlignRightWith()

void FCControl::HorizontallyAlignRightWith ( const FCControl pControl,
double  offset = 0 
)
inline

Specifies a control with which to horizontally align right. All controls set to align with this control align at the location of the one with the largest right value (GetLeft + GetWidth). This function replaces any previous alignment options.

To have an effect, this function must be called before the window is running, It does not work with buttons created using FCCustomWindow::CreateOkButton or FCCustomWindow::CreateCancelButton.

Lua-supported (0.71)

Parameters
pControlthe control to align with: if NULL, then alignment is disabled
offset(optional for C++ and Lua) an amount to offset from the alignment point; default is 0

◆ HorizontallyAlignRightWithFurthest()

void FCControl::HorizontallyAlignRightWithFurthest ( double  offset = 0)
inline

Specifies that this control should align with the control that extends furthest to the right. Calling this function replaces any other control that has been set for horizontal alignment.

To have an effect, this function must be called before the window is running.

Lua-supported (0.71)

Parameters
offset(optional for C++ and Lua) an amount to offset from the alignment point; default is 0

◆ MoveAbsolute()

void FCControl::MoveAbsolute ( float  x,
float  y 
)

Moves the control in absolute coordinates.

Lua-supported (0.63).

Parameters
xPosition for the left side.
yPosition for the top side.

◆ MoveRelative()

void FCControl::MoveRelative ( float  horizmove,
float  vertmove 
)

Moves the control relatively to the current position.

This function only works after the window is running, so Lua scripts must use it in callbacks from FCCustomLuaWindow.

Lua-supported (0.63).

Parameters
horizmoveUnits that the control should be moved horizontally. Positive is to the right.
vertmoveUnits that the control should be moved vertically. Positive is downwards.

◆ RedrawImmediate()

bool FCControl::RedrawImmediate ( ) const

Redraws the control immediately. Calling this allows your program that has blocked the main thread to show immediate results without relinquishing control back to the operating system.

This function may introduce a very small delay that can slightly affect benchmark timings, so use it sparingly when benchmarking.

Lua-supported (0.68)

Returns
true if the control was redrawn, false if the window is not active or there was an error.

◆ Repaint()

virtual void FCControl::Repaint ( )
inlinevirtual

Force a visual update of the control.

Currently only implemented on Windows, but can be overridden in child classes.

Reimplemented in FCCtrlTree.

◆ ResizeRelative()

void FCControl::ResizeRelative ( float  horizresize,
float  vertresize 
)
virtual

Resizes the control relatively to the current size. Top left corner will stay fixed.

Todo:
Resizing vertically does not always work correctly for FCCtrlButton controls on macOS.

Lua-supported (0.63).

Parameters
horizresizeUnits that the control should be resized horizontally.
vertresizeUnits that the control should be resized vertically.

◆ SetAction()

void FCControl::SetAction ( CONTROL_ACTIONS  action)
inline

Sets the dialog acction assigned to the control.

Actions is only used for push buttons.

◆ SetBold()

void FCControl::SetBold ( bool  state)
virtual

Sets the boldface appearance for the control.

This is a legacy function. It does not work with Windows HiDPI awareness if the DPI changes. New code should use CreateFontInfo followed by SetFont.

◆ SetEnable()

void FCControl::SetEnable ( bool  state)
virtual

Sets the enable/grayed state of the control (if user input should be allowed or not).

Technical: This version is virtual, so child classes can override with custom functionality. (If child classes overwrite, this implementation must be called if WindowExists() returns false.)

Lua-supported

◆ SetFont()

void FCControl::SetFont ( const FCFontInfo fontInfo)
virtual

Sets the font information for the text of the control.

The following information is set:

  • Font Family Name
  • Size
  • Bold State
  • Italic State
  • StrikeOut State (Windows only)
  • Underline State (Windows only)

Note that for macOS you must use the font family name (e.g., "Helvetica") rather than a name that contains the style (e.g., "Helvetica Bold"). It is recommended to do the same for Windows. Also, bold, italic, or combined only works on macOS if the font family contains a font with that style or combination of styles.

Some controls on macOS react differently to custom fonts than their counterparts on Windows. Nevertheless, you can at least count on fairly consistent cross-platform behavior with FCCtrlStatic, FCCtrlEdit, and FCCtrlTextEditor.

Lua-supported (0.63)

Parameters
fontInfoThe FCFontInfo instance containing the new font information.

◆ SetHeight()

void FCControl::SetHeight ( float  height)

Sets the height of the control.

Warning
If you call this function while the window is running, always call SetTop afterwards. This works around an issue on macOS where calling SetHeight while the window is running causes buttons and popups to creep up the window.
