State (Property)

In french: Etat

The State property can be used:

in a report.
in a window.
in a page.

In a report, the State property is used to get and change the state:

of a control,
of a report block.

Remark: In a report, the State property can only be used to set the visibility of a control or a block (controls and blocks cannot be grayed out). In this case, this property is available for backward compatibility with WINDEV 5.5 and WEBDEV 1.5. To show or hide a control or a block in a report, use the Visible property.

In a window, the State property is used to get and change the state:

of a window,
of a control or group of controls,
of a table cell or table row,
of a menu option.

Example

// The STC_Static1 control becomes active
STC_Static1.State = Active

// The EDT_Edit1 control becomes active
EDT_Edit1.State = Active
// Modify the content of the Combo Box if it is active
IF COMBO_Combo1.State = Active THEN
COMBO_Combo1 = "<Enter HERE>"
SetFocusAndReturnToUserInput(COMBO_Combo1)
END

// Gray out 4th row in the Table control
TABLE_Customer[4].State = Grayed
// Gray out the 1st cell of column 2
COL_COL2[1].State = Grayed
// Makes the 5th row neither clickable nor editable
TABLE_Customer[5].State = ReadOnlyNoSelection
// Makes the 2nd cell of column 3 neither clickable nor editable
COL_COL3[2].State = ReadOnlyNoSelection
// Makes the cell active
COL_COL3[2].State = Active

Remarks

Visible or invisible control/block

In a report, the only possible state for a control or a block is visible or invisible. To set the visibility of a control, it is recommended to use the Visible property. This property optimizes the management of control visibility.

State of a group of controls

Finding out the state of a group of controls: the state corresponds to the state of the first control in the group.
Modifying the state of a group of controls: all the controls of the group are modified and correspond to the new state.

State of a column in a Table control

If the State property is applied to a column, the state of the entire column is changed (and not only the state of a cell).

Caution: the State property only restricts the state of the column defined in the description window. For example, if the column is read-only, no column cell can become editable.

Tabs and controls of a tab pane

The state of a control in a tab pane depends on the state of the tab:

If the pane is not selected, the control is invisible.
If the pane is selected and invisible, the control is invisible.
If the pane is selected and grayed out, the control is grayed out.
If the pane is selected and disabled, the control is disabled.
If the pane is selected and enabled, the control can be enabled, disabled, grayed out or invisible.

Sidebar and pane controls

The state of a control found in a sidebar pane depends on the state of the pane:

If the pane is not selected, the control is invisible.
If the pane is selected and invisible, the control is invisible.
If the pane is selected and grayed out, the control is grayed out.
If the pane is selected and disabled, the control is disabled.
If the pane is selected and enabled, the control can be enabled, disabled, grayed out or invisible.

Radio Button/Check Box controls and their options

You can modify the state of the control or the state of an option of the Radio Button/Check Box control. An option can be grayed out or enabled.

To modify the state of a Radio Button control:

RADIO_Radio1.State = Grayed
To modify the state of an option in a Radio Button control:

RADIO_Radio1[2].State = Grayed

Caution: The state of an option depends on the state of the Radio Button control. Therefore, if the following operations are performed:

An option is grayed out.
The Radio Button/Check Box control is grayed out.
The Radio Button/Check Box control is re-enabled. The option is still grayed out.

Active control made invisible or not

The Visible property can be used to hide a control (enabled, grayed out or read-only).

When the control is invisible, it loses all the characteristics of its previous state: the control is invisible and it cannot be used. The only way to run its code is to call ExecuteProcess. For example, an invisible control does not respond when using the shortcut. For example, an active button made invisible does not respond when using the shortcut.

To restore the previous state of the control, simply use the Visible property again.

Menu options

The State property determines if the menu option is enabled or greyed out. To show or hide a menu option, use the Visible property.

Limitations

The State property has no effect on reports.

The State property applies only to the following elements:

Button.
Static control.
Edit control.
Image.
Check Box.
Radio Button.
List Box.
Combo Box.
TreeView.
Tab.
Window.
Table.
