[Lazarus] Is TMemo.CaretPos.Y defined in the Qt widgetset?
Is TMemo.CaretPos.Y defined in the Qt widgetset? Memo.CaretPos.Y always returns 0 in the Qt widget set, but it works correctly on GTK2. Is it a known bug? I have tested on Lazarus 1.2.6 and trunk version 48534 on Linux.

[Lazarus] Processing TCoolBar child by IDE
Hi, I have a question / feature request for a TCoolBar at designtime and Lazarus IDE. If I assign a control (e.g. TPanel) to a TCoolBar, a TCoolBand according to the dimensions of TPanels is created. Thats fine! If I change now the dimension of that control (at designtime), at runtime, the width of the TCoolBand got the width of the TCoolBand and the height got the height of the control. There are two features, what would be nice to have: If the height of a TCoolBand child control is changed, the IDE should show the identical height at designtime, like at runtime. If the width of a TCoolBand child control is changed, the width of the TCoolBand should also be changed. As a workaround, you can move the control from the TCoolBand to a other parent, delete the TCoolBand and move the control back to the TCoolBar. Then a TCoolBand with the correct dimensions is created. PS: I know, that the width can be changed by the user at runtime, so that a differentiation of designtime and runtime has to be made. Hope, you understand my poor English. Michael -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Re: [Lazarus] Processing TCoolBar child by IDE
Hi, developing TCoolBar wasn't easy, one must deal with LCL austosizing mechanism, which is very sophisticated. I know that in design-time is not band-height recalculated immediately. The reason is mainly I wanted to do CoolBar efficient and avoid redundant recalculation (LCL triggers many resize events).

I'm happy, that I can use Lazarus with its LCL :)) My request is more to see as a nice to have for the continuity of the Lazarus - RAD. Maybe you or someone else has to made some changes of that component, so this request can flow into it?! BTW did you try TControlBar? Maybe it will suite you better. I've tried the TControlBar (thank you for that hint), but there are also some unwanted bevaviors (like moving a childcontrol upper to top of 0, moves the other controls down). I will see, what the better choice would be. Thank you, for sharing your component.

If you have in unit1 a Form1 with a Button1 component, and Form1 is declared in the Interface section of unit1 (i.e. it's made public), in unit 2 you must have a clause uses unit1 and then you can simply code Form1.Button1.Hide or Form1.Button1.Caption := 'blah'; Only in case of ambiguity you must prepend also the unit name. e.g. unit2 and unit3 both have a Panel1 component and they both have it declared in the Interface section. Then in unit1 you will have uses unit2,unit3. And to operate on them you will code: unit2.Panel1.hide; unit3.Panel1.show; If there's no ambiguity, it's unnecessary.
