ScrollWheelWithSelectionStyle
touchgfx/containers/scrollers/ScrollWheelWithSelectionStyle.hpp
A scroll wheel is very much like the digit selector on a padlock with numbers. The digits always snap into place and exactly one number is always the "selected" number. Similar to an ordinary ScrollWheel, but with a different style for the selected item which can thus be bold, have a different color or similar effect to highlight it and help create a 3D effect using very few resources.

Reimplements: touchgfx::ScrollBase::initialize
itemChanged
virtual void itemChanged | ( | int | itemIndex | ) | |
Inform the scroll list that the contents of an item has changed and force all drawables with the given item index to be updated via the callback provided.
This is important as a circular list with very few items might display the same item more than once and all these items should be updated.
itemIndex | Zero-based index of the changed item. |
Reimplements: touchgfx::ScrollBase::itemChanged
ScrollWheelWithSelectionStyle
setCircular
virtual void setCircular | ( | bool | circular | ) | |
Sets whether the list is circular (infinite) or not.
A circular list is a list where the first drawable re-appears after the last item in the list - and the last item in the list appears before the first item in the list.
circular | True if the list should be circular, false if the list should not be circular. |
Reimplements: touchgfx::ScrollBase::setCircular
setDrawables
virtual void setDrawables | ( | DrawableListItemsInterface & | drawableListItems , | ||
GenericCallback< DrawableListItemsInterface *, int16_t, int16_t > & | updateDrawableCallback , | ||||
DrawableListItemsInterface & | centerDrawableListItems , | ||||
GenericCallback< DrawableListItemsInterface *, int16_t, int16_t > & | updateCenterDrawableCallback | ||||
) |
Setups the widget.
Numerous parameters control the position of the widget, the two scroll lists inside and the values in them.
drawableListItems | Number of drawables in outer array. |
updateDrawableCallback | The callback to update a drawable. |
centerDrawableListItems | Number of drawables in center array. |
updateCenterDrawableCallback | The callback to update a center drawable. |
setDrawableSize
virtual void setDrawableSize | ( | int16_t | drawableSize , | ||
int16_t | drawableMargin | ||||
) |
Sets drawables size.
The drawable is is the size of each drawable in the list in the set direction of the list (this is enforced by the DrawableList class). The specified margin is added above and below each item for spacing. The entire size of an item is thus size + 2 * spacing.
For a horizontal list each element will be drawableSize high and have the same width as set using setWidth(). For a vertical list each element will be drawableSize wide and have the same height as set using setHeight().
drawableSize | The size of the drawable. |
drawableMargin | The margin around drawables (margin before and margin after). |
Reimplements: touchgfx::ScrollBase::setDrawableSize
setHeight
virtual void setHeight | ( | int16_t | height | ) | |
Sets the height of this drawable.
height | The new height. |
Note
For most Drawable widgets, changing this does normally not automatically yield a redraw.Also sets the height of the children.
Reimplements: touchgfx::ScrollBase::setHeight
setHorizontal
virtual void setHorizontal | ( | bool | horizontal | ) | |
Sets a horizontal or vertical layout.
If parameter horizontal is set true, all drawables are arranged side by side. If horizontal is set false, the drawables are arranged above and below each other (vertically).
horizontal | True to align drawables horizontal, false to align drawables vertically. |
Note
Default value is false, i.e. vertical layout.
Reimplements: touchgfx::ScrollBase::setHorizontal
setNumberOfItems
virtual void setNumberOfItems | ( | int16_t | numberOfItems | ) | |
Sets number of items in the DrawableList.
This forces all drawables to be updated to ensure that the content is correct. For example a date selector might switch number of days between 28, 29, 30, and 31 depending on the month. A circular list might show 27-28-29-30-31 and might need to update this to show 27-28-1-2-3.
numberOfItems | Number of items. |
Note
The DrawableList is refreshed to reflect the change.
Reimplements: touchgfx::ScrollBase::setNumberOfItems
setSelectedItemExtraSize
virtual void setSelectedItemExtraSize | ( | int16_t | extraSizeBefore , | ||
int16_t | extraSizeAfter | ||||
) |
Sets selected item extra size to make the size of the area for the center drawables larger.
extraSizeBefore | The extra size before. |
extraSizeAfter | The extra size after. |
setSelectedItemMargin
virtual void setSelectedItemMargin | ( | int16_t | marginBefore , | ||
int16_t | marginAfter | ||||
) |
Sets margin around selected item.
This like an invisible area added before and after the selected item (including extra size).
marginBefore | The margin before. |
marginAfter | The margin after. |
setSelectedItemOffset
virtual void setSelectedItemOffset | ( | int16_t | offset | ) | |
Sets selected item offset, measured in pixels, from the edge of the widget.
The offset is the relative x coordinate if the ScrollWheel is horizontal, otherwise it is the relative y coordinate. If this value is zero, the selected item is placed at the very start of the widget.
offset | The offset. |
Reimplements: touchgfx::ScrollWheelBase::setSelectedItemOffset
setSelectedItemPosition
virtual void setSelectedItemPosition | ( | int16_t | offset , | ||
int16_t | extraSizeBefore , | ||||
int16_t | extraSizeAfter , | ||||
int16_t | marginBefore , | ||||
int16_t | marginAfter | ||||
) |
Sets the selected item offset.
This is the distance from the beginning of the ScrollWheel measured in pixels. The distance before and after that should also be drawn using the center drawables - for example to extend area of emphasized elements - can also be specified. Further, if a gap is needed between the "normal" drawables and the center drawables - for example to give the illusion that that items disappear under a graphical element, only to appear in the center.
This is a combination of setSelectedItemOffset, setSelectedItemExtraSize and setSelectedItemMargin.
offset | The offset of the selected item. |
extraSizeBefore | The extra size before the selected item. |
extraSizeAfter | The extra size after the selected item. |
marginBefore | The margin before the selected item. |
marginAfter | The margin after the selected item. |
setWidth
virtual void setWidth | ( | int16_t | width | ) | |
Sets the width of this drawable.
width | The new width. |
Note
For most Drawable widgets, changing this does normally not automatically yield a redraw.Also sets the width of the children.
Reimplements: touchgfx::ScrollBase::setWidth

refreshDrawableListsLayout
void refreshDrawableListsLayout | ( | ) |

Sets display offset of first item.
offset | The offset. |
