Clicked back on the form on a different component and selection is locked on the last selected component. Couldn't close down Lazarus either, needed to ctrl C from calling terminal.

Mattias seems to have this worked out already in CVS as of this morning, so if you want to update your version this problem should go away. It apears that it was a double click issue, where when you double clicked a component it grabbed focus and didn't let go. While there may be more issues, right now the Form Editor itself apears to be working properly, and pretty stable as well. Woohoo!

Okay, thanks for that.

Hi Mattias,

cvs update;make clean all

single clicking on the calendar, some of the single clicks are still missed. Scrolling the year forward with quickly, about 1 in 4 are lost. Scrolling more slowly, about 1 in 8 are lost. Repeated this with toggle box too.

In the OI, clicked on the component popup and only got the current control (static text selected, there is a text, memo and listbox on the form). Clicked back on the form on a different component and selection is locked on the last selected component. Couldn't close down Lazarus either, needed to ctrl C from calling terminal.

Hope this helps a bit.

Cheers

Hello,

I tried to compile lazarus; It fails, because you use expressions like

  I += 1;

Either adapt the makefiles so the -Sc option is passed, either don't use these C constructs.

After fixing that, everything went fine. Great job !

Michael.

Hi,

Updates:

- source editor: ctrl+mouse now marks the word under the mouse as link pressing ctrl+left mouse button works as find declaration
- fixed mouse double click recognition. This bug was the reason for some of the ignored single clicks
- form editing: click on OI will now focus the edit control
- fixed mouse capturing: (Designer Capturing Bug)
- gtk-interface now sends mouse events directly to LCL
- gtk-interface now updates the mouse capture handle on every mouse message
- gtk-interface: GetCoreChild returns now NIL as default
- fixed TSpeedButton.SetDown and Invalidate
- form editing: loading forms now creates all TComponentInterfaces
- form editing: fixed crash bug on deleting components
- form editing: fixed moving child components

The gtk interface has mistaken your fast clicks as double clicks. I added another check: Only controls with csDoubleClick will now get double clicks. And Excluded csDoubleClicks from TCalendar.ControlStyle.

There seems to be another designer capturing bug...

Mattias

Hi all,

Updates:
- added mem manager for gtk-interface GDIObjects and DeviceContexts
- fixed heaptrc mem leaks of IDE/LCL
- fixed gdk_gc leaks
- accelerated synedit painting
- popupmenu items for bookmarks in source editor are now checked
- better theme support from Andrew: styles for LCL custom widgets can now be copied from any gtk widget type. For example the TSpeedButton now uses the style of gtkbutton.
- form editing: renaming a form in the OI now renames the form and its class in the unit, changes the class name of the designed form and changes the CreateForm statement in the program source.
- minors: better bracket hilighting, fixed TMenuItem.AutoCheck, reduced freezing during compilation

I just checked this out, and you should never have to kill the program, as menu shortcuts will still work, even when the mouse is captured by a component as you describe. When this happened to me, I just did a Alt F to get to the file menu and scrolled down to quit, I got a prompt to save, and the mouse then worked to click the Yes button, and Lazarus closed cleanly. I did a further test, and found that if you open a popup form, then the control in question loses the mouse. So for instance I had the mouse locked on a button, so did a Ctrl F, to open the find dialog, clicked the Close button, and the mouse was no longer caught on the button. Kind of clumsy, but until Matthias, or someone else can figure out what's going on here, it seems to work.

I replaced the C constructs.

Mattias

Hi, it seems like form editing is getting improved every day, thanks. Here is a little change that i made to MoveSelectionWithSnapping so the form is only invalidated when it needs .

Thx. Applied.

Plz zip diffs before you attach them. Sending them as text can destroy the line breaks.

Mattias

Hi Mattias,

Sorry about that one. I set the source directory in the files section of Environment -> General Options and the OnClick was created correctly.

Thanks for that advice from someone on that list whose original email I've lost.

Cheers

Hi all,

I have changed some central parts of the LCL and GTK<->LCL paint system. I have disabled/removed some of the old workarounds and I hope that everything works well.

Updates:

- SetWindowOrgEx and MoveWindowOrgEx now sets the origin of a DeviceContext. All graphic functions were altered.
- The child controls of a TWinControl are now splitted into TControls and TWinControls as in the VCL.
- TControls (that are not TWinControls) are now painted with correct clipping and origin. That's why now for example TBevel works.
- GetWindowOrgEx now returns the origin of the Drawable and not of the owner Widget.
- Form editing: The designer now uses a faster devicecontext system, which reduces SaveDC/RestoreDC calls and provides a canvas.
- Form editing: all designer draw functions now paint to the correct position
- Form editing: all client areas now show a grid
- Fixed many controlstyles (e.g csOpaque was missing and there were too many csDoubleClicks/csTripleClicks).
- Added 'Use Display' to the 'Run Parameters' dialog

Mattias

Hi,

Updates:

- fixed gtk warnings of TSpinEdit
- codetools: fixed collection of procs (e.g. OI event combobox)
- form editing: fixed auto removing of child controls, fixed OI events combo, fixed cleaning up .lrs files, fixed creating new .lrs files, fixed removing non visual components, fixed selecting non visual components
- open recent file/project now removes items, if file not found
- improved uncapturing
- reduced paint messages and creating/freeing DCs
- implemented the environment options in the run parameter dialog

from Andrew:
- Support for Mnemonic (aka '&') Shortcut Keys to TButton/TBitBtn
- property editors: Prefix support to Values, so for instance SpeedButton Captions which Contain an '&' will display an underscore in the property editor the same way it will on the Button

Mattias

OnClick and I got an orange line on the Interface Uses clause.

This sounds too me like your FPC source directory hasn't been set. For some reason trying to create an event handler for some things, like OnClick, raises an IDE 'SysUtils Not Found' or the like if your FPC Source Path haven't been set properly. Try making sure it's valid in your General Options. I think this is simply screwy behaviour in the IDE since it shouldn't need to have FCL/RTL Sources in the path to set an event handler, only to 'open file at cursor' etc.

Mattias, Jesus,

Thank you both. I get all of my mouse clicks on the calendar now. It almost feels as good as using Delphi in Win32 !

Just a quick question... I dropped a button on the form and then went to the events tab of the OI and tried to make an event handler for the OnClick and I got an orange line on the Interface Uses clause. However, if I double click on MouseMove, I get a function created (and I made a simple test handler and it worked like a charm !). Is there something wrong with my config or are onclick handlers for buttons not done yet.

The screen updates when moving controls around now has much more efficient redrawing, which makes it much better to use.

Again, thanks for the fantastic work.

Cheers
DC

TButton.OnClick is working.
The test if a method is compatible is not yet complete, so the OI does not show the methods for OnMouseMove in the combobox. But this is another problem.

Just creating a new form, adding a Button and create the event for OnClick works for me. Can you tell the exact steps to reproduce this error?

Mattias
