IDE Window: Object Inspector
The "Object Inspector" window allows you to explore and edit the properties of objects. Objects here are TPersistent descendants like a TForm or a TButton or a TOpenDialog.
On the top there is a tree showing the components of the currently edited designer form (or datamodule or frame or whatever).
The biggest part of the Object Inspector are the 3 property grids called 'Properties', 'Events' and 'Favorites'. Each property grid show a subset of the published properties of the selected components.
The Object Inspector is a useful tool for debugging your own programs. How to add the Object Inspector to your own programs is demonstrated in examples/objectinspector.
|Up, Down||Navigate rows|
|Alt + Left||Collapse level|
|Alt + Right||Expand level|
|Ctrl + Enter||Cycle enumerated values|
You can use keyboard for fast Property Name search and edit.
Let's assume you want to modify Form's Caption and Width properties
- Click Form. - Go to Object inspector (caret is on Property Value column). - Press Tab to switch to Property Name column (caret will disappear from Value column). - Type "caption". Property row "Caption" will be found. - Press Tab or Enter to go to Property Value and edit it.
- Press Tab to switch to Property Name column again. - Type "width". Width row will be found. - Press Tab or Enter and edit it.
If you misspelled property name you can press Esc and retype it. Or you can use Backspace to remove few last chars.
Set to default
Set the property value to the default value. For example:
property Position: TPosition read FPosition write SetPosition default poDesigned;
Here poDesigned is the default.
Note: Not every property has a default value. Default values defined by the stored functions are ignored by this function.
Discard changes of the edit field and restore the value of the current property. Do not confuse this with the value from the disk.
Jump to declaration
Jump to the source declaration of the property. This will be the last one. For example TForm.Left is published in the class TForm and defined in TControl. You can jump easily to the other declaration, by doing a find declaration on the name again and again, until you are the lowest definition (Alt+Up or Ctrl+LeftClick). You can jump back with Ctrl+H.
