Components
EC-Controls are installed to the tab EC-C on the Lazarus component palette.
Components below are listed in order of their appearance on the component palette. All screenshots are taken from KDE4 (Lazarus+Qt).
Visual
TECBevel
TECLink
TECImageMenu
Vertical menu with images. Similar component is frequently used in KDE4 applications.
TECImageMenu makes properties published only.
TECImageMenu can have focus and can be reached by Tab key (when TabStop = True, which is default).
TECImageMenu can be controlled by mouse, by keyboard or by code.
Mouse
Simply left-click on menu item.
Middle-click or right-click selects an item but does not click.
Mouse wheel moves the selection but does not click.
Keyboard
Space nad Enter: click on the selected item.
Arrow Up, Arrow Down, Page Up, Page Down, Home and End: moves the selection but does not click.
Acceleration key (Alt + Key) selects and clicks the relevant item (menu doesn't need to be focused)..
TECSpinBtns
TECSpinEdit
TECSwitch
An alternative to TCheckBox. Similar component exists in GTk3.
TECSwitch can have focus and can be reached by Tab key (when TabStop = True, which is default). TECSwitch can be controlled by mouse, by keyboard or by code.
Mouse
Left-click on switch area (out of knob) will change the State*.
Left-click on the knob and holding the left-mouse button down will capture mouse and knob can be moved even if the mouse-cursor leaves the area of the switch.
Keyboard
Space or Enter changes the State* (only when focused).
Acceleration key (Alt + Key) changes the State* (doesn't need to be focused).
Code
Simply by assigning any State* or Checked property:
Checked := True; //False State := cbChecked; //cbGrayed, cbUnchecked
*) Property State is always changed from checked to unchecked, from grayed to unchecked or from unchecked to checked.
TECSpeedBtn
TECEditBtn
TECColorBtn
TECComboBtn
TECColorCombo
TECHeader
TECCheckListBox
TECSlider
An advanced alternative to TTrackBar.
TECSlider can have focus and can be reached by Tab key (when TabStop = True, which is default).
TECSlider is based on double precision variables. TECSlider can be controlled by mouse, by keyboard or by code.
Mouse
Left-click on Slider area (out of Knob) will move the knob by PageSize (or less, if mouse cursor is nearer).
Double-click or Middle-click will move the knob immediately to the mouse cursor (or to the Min/Max, if click is done out of groove and scale area).
Left-click on the knob and holding the left-mouse button down will capture mouse and knob can be moved even if the mouse-cursor leaves the area of the slider.
Mouse wheel moves knob up/down regardless of the Reversed property. In case of horizontal slider rolling up/down moves knob to the left/right, again, regardless of the Reversed property.
The increment is:
Mouse wheel: Increment*Mouse.WheelScrollLines
Ctrl + mouse wheel: Increment.
Keyboard
Space: moves knob to the middle of the groove or to the ProgressMiddlePos in case of ProgressFromMiddle = True
0-9: moves the knob to position which is the integer multiplier of the PageSize (i.e. 0, 10, ..., 90 for PageSize = 10).
PgUp: decreases Position by PageSize
PgUp: increases Position by PageSize
Home: moves the Knob to Min
End: moves the Knob to Max
+: increases Position by Increment
-: decreases Position by Increment
Ctrl + ArrowUp: decreases* Position by Increment
Ctrl + ArrowLeft: decreases* Position by Increment
Ctrl + ArrowDown: increases* Position by Increment
Ctrl + ArrowRight: increases* Position by Increment
*) valid for Reversed = False. When Reversed = True works oppositely.
Code
Simply by assigning any floating-point value to property Position:
Position := 10.5;
If the value is out of range (lesser than Min or greater than Max) then Position will be Min or Max.
TECProgressBar
An advanced alternative to TProgressBar.
TECProgressBar is based on double precision variables. TECProgressBar cannot have focus. It can be controlled by code only.
TECPositionBar
TECSpinPosition
TECRuler
An advanced ruler.
TECRuler cannot have focus.
TECRuler just displays scale. It can have fixed or movable pointer optionally.
