Target-alignment-and-drop control for editing electronic documents
View Patent ↗A target-alignment-and-drop control for an electronic document editing tool which ensures that objects are inserted only in valid drop target areas and are aligned according to predetermined alignment rules.
1. A computer-implemented method for positioning an object in a region of text in an electronic document, the region of text having one or more predefined valid drop target areas and one or more predefined invalid drop target areas, the method comprising:
detecting activation of a target-alignment-and-drop control with respect to an object;
monitoring a position of a cursor as it is dragged from a first position to a second position in the electronic document;
determining whether the second position is within boundaries of any of the predefined valid drop target areas and selecting a particular one of the predefined valid drop target areas if the second position is within the boundaries of the particular one valid drop target area;
determining a plurality of different alignment areas for the selected predefined drop target area, each respective alignment area having associated therewith a different set of alignment rules which dictate placement of an object within the selected predefined drop target area for the respective determined alignment area;
selecting a current alignment area in which the second position is located;
displaying an alignment indicator which indicates a general position of alignment where the object will be inserted if the target-alignment-and-drop control is released;
detecting a release of the target-alignment-and-drop control; and
inserting the object in the selected drop target area such that the object is positioned and aligned within the current alignment area of the selected predefined drop target area according to the alignment rules associated with the current alignment area.
2. The method of claim 1 , wherein the object is not inserted in any area of the electronic document until the activated target-alignment-and-drop control is released.
3. The method of claim 1 , wherein text in the selected drop target area is reformatted to flow around the inserted object according to alignment rules associated with the selected alignment area.
4. The method of claim 1 , wherein the electronic document is a web page being edited.
5. Non-transitory computer readable storage tangibly embodying program instructions which, when executed by a computer, implement a method for positioning an object in a region of text in an electronic document, the region of text having one or more predefined valid drop target areas and one or more predefined invalid drop target areas, the method comprising:
detecting activation of a target-alignment-and-drop control with respect to an object;
monitoring a position of a cursor as it is dragged from a first position to a second position in the electronic document;
determining whether the second position is within boundaries of any of the predefined valid drop target areas and selecting a particular one of the predefined the valid drop target areas if the second position is within the boundaries of the particular one valid drop target area;
determining a plurality of different alignment areas for the selected predefined drop target area, each respective alignment area having associated therewith a different set of alignment rules which dictate placement of an object within the selected predefined drop target area for the respective determined alignment area;
selecting a current alignment area in which the second position is located;
displaying an alignment indicator which indicates a general position of alignment where the object will be inserted if the target-alignment-and-drop control is released;
detecting a release of the target-alignment-and-drop control; and
inserting the object in the selected drop target area such that the object is positioned and aligned within the current alignment area of the selected predefined drop target area according to the alignment rules associated with the current alignment area.
6. The non-transitory computer readable storage of claim 1 , wherein the object is not inserted in any area of the electronic document until the activated target-alignment-and-drop control is released.
7. The non-transitory computer readable storage of claim 1 , wherein text in the selected drop target area is reformatted to flow around the inserted object according to alignment rules associated with the selected alignment area.
8. The non-transitory computer readable storage of claim 1 , wherein the electronic document is a web page being edited.
9. A system, comprising:
input means for receiving user input;
a display for displaying an editable electronic document; and
a processor executing computer readable instructions which implement a method for positioning an object in a region of text in the electronic document, the region of text having one or more predefined valid drop target areas and one or more predefined invalid drop target areas, the method including the steps of detecting activation of a target-alignment-and-drop control with respect to an object; monitoring a position of a cursor as it is dragged from a first position to a second position in the electronic document; determining whether the second position is within boundaries of any of the predefined valid drop target areas and selecting a particular one of the predefined valid drop target areas if the second position is within the boundaries of the particular one valid drop target area; determining a plurality of different alignment areas for the selected predefined drop target area, each respective alignment area having associated therewith a different set of alignment rules which dictate placement of an object within the selected predefined drop target area for the respective determined alignment area; selecting a current alignment area in which the second position is located; displaying an alignment indicator which indicates a general position of alignment where the object will be inserted if the target-alignment-and-drop control is released; detecting a release of the target-alignment-and-drop control; and inserting the object in the selected drop target area such that the object is positioned and aligned within the current alignment area of the selected predefined drop target area according to the alignment rules associated with the current alignment area.
10. The system of claim 9 , wherein the object is not inserted in any area of the electronic document until the activated target-alignment-and-drop control is released.
11. The system of claim 9 , wherein text in the selected drop target area is reformatted to flow around the inserted object according to alignment rules associated with the selected alignment area.
12. The system of claim 9 , wherein the electronic document is a web page being edited.
