| Summary | 0037467: Form Resize Not Firing Correctly | ||||
| Description | The form resize event is only fired once; after you have finished resizing, it should be firing every time width,height etc changes. This is only a recent change. Working fine with Lazarus 2.1.0 r63401 FPC 3.3.1 x86_64-win64-win32/win64 Not working with Lazarus 2.1.0 r63673 FPC 3.3.1 x86_64-win64-win32/win64 | ||||
| Steps To Reproduce | Sample Project attached, if you resize the form, the trigger is updated only when mouse is released. Note the project is saved for Project version 2 and above. | ||||

Tested with Lazarus 2.1.0 r63823 FPC 3.3.1 x86_64-win64-win32/win64 Problem still exists, attached projects that keeps track of what events are fired, form onchangebounds and onresize are not fired when resizing in Trunk This is a major issue... |
|
|
Can you please find which revision between r63401 and r63673 caused the regression. https://wiki.freepascal.org/How_do_I_create_a_bug_report#Regression_caused_by_a_certain_revision |
|
|
rev 63557 works 63558 and above i cant compile, various errors |
|
|
Ok, it was r63577. I reopened issue 0036127. Any ideas of how to fix it? |
|
|
This got fixed by a patch from Joeny Ang. Please test. |
|
|
Tested Even though the events are now firing, it is having a drastic effect on resizing controls. attached is a test project that you can turn on/off whether application.processmessages is used after resize, and enable formbegin/end update during resize. The difference is around 4 times slower in new svn My apps have logic for resizing that alters what is shown dependent on size of form, and a smooth resize is paramount, test app uses just panel,label,image anf button components, so you should see the implication of the update ps Juha Manninen, Should I leave this here, or create new bug or add to the linked one above. |

Just tried latest svn, and form resize is NOT firing again. Lazarus 2.1.0 r63882 FPC 3.2.1 x86_64-win64-win32/win64 |
|
|
Please mark this as NOT resolved and NOT fixed. |
|
|
@josh, you can also reopen your own reports. Reopening now... |
|
|
This seems to work also after r63888 (issue 0036127). Resolving. |
