Detailed description
Previously, there was no way to filter quick searches. Users had no menu to toggle certain settings when searching. I have added this menu in QuickFilterView and ComboQuickFilterView widgets as requested in #2230.
I have read SearchBarWidget to understand the requirements of the issue and started working right after, The menu I have created is a line-edit menu instead of creating a separate button. I have achieved this using QLineEdit::addAction() as advised by one of the maintainers.

Changes Made

• src/widgets/QuickFilterView.h: Added member variables, new signal, and helper method
• src/widgets/QuickFilterView.cpp: Implemented menu creation and filter logic
• src/widgets/ComboQuickFilterView.h: Same additions for consistency
• src/widgets/ComboQuickFilterView.cpp: Same implementation for consistency

References

• Inspired by how SearchBarWidget handles filter options

• Referenced Qt documentation: https://doc.qt.io/qt-6/qlineedit.html#addAction

• Uses SearchOption enum from src/common/CutterSearchable.h

• Code follows Cutter's coding style guidelines

Test Plan

1. Open Cutter and load a binary

2. Verify the cog icon appears

   • Look for a small cog/settings icon on the LEFT side of the filter text input
   • The icon should be inside the line-edit, not outside

3. Click the cog icon

   • A dropdown menu should appear with 3 options:
     • ☐ Case Sensitive
     • ☐ Exact Match
     • ☐ Regular Expression

4. Test toggling options

   • Click each option to toggle the checkbox
   • Verify the checkbox state changes visually
   • Try typing in the filter while options are toggled

5. Verify filtering behavior

   • With "Case Sensitive" checked: searches should be case-sensitive
   • With "Exact Match" checked: only exact matches should be found
   • With "Regular Expression" checked: search should accept regex patterns

6. Test ComboQuickFilterView (widgets using combo box + filter)

   • Repeat steps 2-6 for any widget using ComboQuickFilterView
   • Verify same menu behavior

closes #2230.

you added a lot of useless files. there are even binaries. this is not ok

please follow the instructions on how to build cutter and dont commit llm/ai nonsense

[RealAhmedKhairi]

@wargio I have cleaned everything up.

[wargio]

I feel like the code repeats itself, maybe this could go into a class? @notxvilka what do you think?

Agreed, See #3580 it moves the old duplicate logic in both to a new class

[RealAhmedKhairi]

@PremadeS What do I have to do now?

[PremadeS]

None of the options work, because there is no logic to handle case sensitive, exact match etc
Please test the PR fully before committing

@PremadeS What do I have to do now?

Keep it as it is, just make sure it works

[RealAhmedKhairi]

@PremadeS I am sorry, I have been a little busy with my college midterms. I will start working on the functionality as soon as possible.

[PremadeS]

Filter doesn't update according to text unless any option is changed
Also the item count is not working properly

[RealAhmedKhairi]

@PremadeS I will start working on making CI green.

@PremadeS I will start working on making CI green.

It's most likely failing due to #3600

[RealAhmedKhairi]

@PremadeS Should I wait until #3600 is merged?
