hi all,

in one project there is a form A which use a parent form B.

in form A there is a TEdit component, if this component is moved vertically in the IDE, it can be correctly displayed when the application runs. But if this componet is moved  horizontally in the IDE, it turns back to the original position when the application runs.

following are some related information of this TEdit component:

Align: alNone
left: 200

any suggestion?

btw, are there special books or ressource to explain how to design layout in Delphi?

thanks,

wantime

When Form B calls form A do you set the Left value of the TEdit component in your code (e.g. OnFormA Show or even from Form B) ?

the biggest problem is with default values
and if they are stored or not in the dfm

this is not so for positioning, but i'm just trying to explain with the property Left

sample:
  default value for property Edit.Left: 50
  if default value > not stored in dfm

start situation
Form A dfm
  > Edit1.Left = 60

Form B dfm (inherited from Form A)

Form B will only store the differences with Form A

situation 2: change form B
Form B
  > Edit1.Left = 80
> save form B > no problem

situation 3: change form A
Form A
  > Edit1.Left = 70
> save form A

the component Edit1 will remain on Edit1.Left = 80 on Form B

there may be other factors  too
 like anchors, margins, oldcreateorder

You probably have code thats specifically setting the the edit's left property or some event that when triggered repositions the Edit

In an inherited form, if you move a control, the controls position is saved in the dfm and thats whats loaded.

You should be able to, easily, create a do nothing example project that you CAN post on this site.  Then the experts would at least have something to work with...
